[N-Benzyl-N-(2-phenyl-eth-yl)di-thio-carbamato-κ2S,S']tri-phenyl-tin(IV) and [bis-(2-meth-oxy-eth-yl)di-thio-carbamato-κ2S,S']tri-phenyl-tin(IV): crystal structures and Hirshfeld surface analysis.

The crystal and mol-ecular structures of two tri-phenyl-tin di-thio-carbamates, [Sn(C6H5)3(C16H16NS2)], (I), and [Sn(C6H5)3(C7H14NO2S2)], (II), are described. In (I), the di-thio-carbamate ligand coordinates the SnIV atom in an asymmetric manner, leading to a highly distorted trigonal-bipyramidal coordination geometry defined by a C3S2 donor set with the weakly bound S atom approximately trans to one of the ipso-C atoms. A similar structure is found in (II), but the di-thio-carbamate ligand coordinates in an even more asymmetric fashion. The packing in (I) features supra-molecular chains along the c axis sustained by C-H⋯π inter-actions; chains pack with no directional inter-actions between them. In (II), supra-molecular layers are formed, similarly sustained by C-H⋯π inter-actions; these stack along the b axis. An analysis of the Hirshfeld surfaces for (I) and (II) confirms the presence of the C-H⋯π inter-actions but also reveals the overall dominance of H⋯H contacts in the respective crystals.

Chemical context

Among the varied motivations for investigan class="Chemical">ting organotin di­thio­carbamate compounds, i.e. RSn(S2CNRR′)4– where R, R′ = alkyl, aryl, most relate to their biological activities and their usefulness as mol­ecular, single-source precursors for the formation of tin sulfide nanoparticles (Tiekink, 2008 ▸). In terms of the latter, while triorganotin di­thio­carbamates, i.e. with n = 3, have been examined in this context (Kana et al., 2001 ▸), di- and mono-organotin derivatives often provide more effective precursors (Ramasamy et al., 2013 ▸). By contrast, significant inter­est in the biological effects of triorganotin di­thio­carbamates continues. Hence, a wide variety of biological applications of triorganotin di­thio­carbamates, i.e. directly related to the title compounds, have been investigated. Thus, anti-bacterial (Muthalib et al., 2015 ▸), larvicidal (Song et al., 2004 ▸), including against mosquito larvae (Basu Baul et al., 2005 ▸), insecticidal (Awang et al., 2012 ▸; Safari et al., 2013 ▸) and anti-leishmanial activities (Ali et al., 2014 ▸) have been investigated. However, most activity has been directed towards evaluating their potential as anti-cancer agents (Tiekink, 2008 ▸; Khan et al., 2014 ▸, 2015 ▸). It was in this context and during on-going structural studies of organotin di­thio­carbamates (Muthalib et al., 2014 ▸; Mohamad et al., 2016 ▸) that the title compounds were synthesized. Herein, the crystal and mol­ecular structures of (C6H5)3Sn[S2CN(Ben)CH2CH2Ph] (I) and (C6H5)3Sn[S2CN(CH2CH2OMe)2] (II) are reported along with a detailed analysis of the supra­molecular association operating in their crystal structures by means of Hirshfeld surface analysis.

Structural commentary

The mol­ecular structure of (I) is shown in Fig. 1 ▸ and selected geometric pn class="Chemical">arameters are collected in Table 1 ▸. The tin atom is bound to three phenyl groups and to the di­thio­carbamate ligand. The latter coordinates asymmetrically with Δ(Sn—S), being the difference between the Sn—Slong and Sn—Sshort bond lengths, of 0.42 Å. This asymmetry is reflected in the relatively large disparity in the associated C—S bond lengths with the bond involving the tightly bound S1 atom being significantly longer than the bond involving the S2 atom, Table 1 ▸. Such a great difference might imply a monodentate mode of coordination for the di­thio­carbamate ligand and the adoption of a tetra­hedral coordination geometry. However, the range of tetra­hedral angles if this were the case is over 30°, i.e. from a narrow 92.98 (4)° for S1—Sn—C17 to a wide 124.31 (4)° for S1—Sn—C29. The wide angle is due to the close approach to the tin atom of S2. Further, the Sn—C17 bond length is systematically longer than the other Sn—C bond lengths, an observation ascribed to the C17 atom being approximately trans to the incoming S2 atom, Table 1 ▸. Thus, the coordination geometry is best described as being based on a C3S2 donor set. The geometry is not ideal with the value of τ of 0.57, cf. τ values of 0.0 and 1.0 for ideal square–pyramidal and trigonal–bipyramidal geometries, respectively (Addison et al., 1984 ▸), suggesting a small distortion towards trigonal–bipyramidal. Distortions from the ideal can be related to the disparate Sn—donor atom bond lengths and the acute chelate angle, Table 1 ▸.

The mol­ecular structure of (II) (Fig. 2 ▸) ben class="Chemical">ars many similarities with that just described for (I). The value of Δ(Sn—S) of 0.64 Å is even greater than that of (I), indicating a more asymmetric mode of coordination of the di­thio­carbamate ligand. This difference is also reflected in the associated C—S bond lengths, following the same trend as for (I) but, with Δ(C—S) of 0.08 Å cf. 0.06 Å for (I). This being stated, the Sn—C14 bond length of 2.1608 (14)°, with the C14 atom being trans to the S2 atom, is the longest of all six Sn—C bonds in (I) and (II). The range of tetra­hedral angles, i.e. 90.94 (4)° for S1—Sn—C14 to 119.54 (5)° for C8—Sn—C20, is slightly narrower at less than 30°. The value of τ computes to 0.58, i.e. virtually identical to that in (I).

Supra­molecular features

Despite there being five aromatic rings in the mol­ecule of (I), the closest face-to-face contact between rings is > 4.0 Å. The only points of contact between mol­ecules in the mol­eculn class="Chemical">ar packing identified by PLATON (Spek, 2009 ▸) are those of the type C—H⋯π. Each of the rings of the di­thio­carbamate ligand donates a hydrogen atom to a different tin-bound phenyl ring with the result that a supra­molecular chain is formed along the c-axis direction, Table 2 ▸ and Fig. 3 ▸ a. The chains pack without directional inter­actions between them, Fig. 3 ▸ b.

Even though there are n class="Chemical">oxygen atoms in the mol­ecule of (II), the supra­molecular association is dominated by C—H⋯π contacts involving methyl-C—H and Sn-bound-phenyl-C—H as donors and only two of the Sn-bound phenyl rings as acceptors, as the (C14–C19) ring accepts two inter­actions, Table 3 ▸. The result of this association is the formation of supra­molecular layers in the ac plane, Fig. 4 ▸ a. The layers stack along the b axis without directional inter­actions between them, Fig. 4 ▸ b.

Hirshfeld surface analysis

Crystal Explorer (Wolff et al., 2012 ▸) was used to generate Hirshfeld surfaces mapped over d norm, shape-index and electrostatic potential. The electrostatic potentials were calculated using TONTO (Spackman et al., 2008 ▸; Jayatilaka et al., 2005 ▸) integrated into Crystal Explorer, wherein the respective experimental structure was used as the input to TONTO. Further, the electrostatic potentials were mapped on Hirshfeld surfaces using the STO-3G basis set at the Hartree–Fock level of theory over ranges ± 0.037 au. and ± 0.048 au. for (I) and (II), respectively. The contact distances d i and d e from the Hirshfeld surface to the nen class="Chemical">arest atom inside and outside, respectively, enable the analysis of the inter­molecular inter­actions through the mapping of d norm. The combination of d e and d i in the form of two-dimensional fingerprint plots (McKinnon et al., 2007 ▸) provides a useful summary of inter­molecular contacts in the respective crystal.

The different shapes of Hirshfeld surfaces for mol­ecules (I) and (II) arise from the asymmetric geometries resuln class="Chemical">ting from the different di­thio­carbamate-bound functional groups, i.e. phenyl and meth­oxy groups in (I) and (II), respectively, Fig. 5 ▸. The images of the Hirshfeld surface mapped over electrostatic potential for (I) and (II) display dark-red and dark-blue regions, assigned to negative and positive potentials, respectively, and are localized near their respective functional groups. The absence of conventional hydrogen bonds in the crystals of (I) and (II) is consistent with the non-appearance of characteristic red-spots in the Hirshfeld surface mapped over d norm (not shown). The curvature of the Hirshfeld surfaces around the phenyl rings participating as acceptors in the C—H⋯π contacts determine the strength of these inter­actions in the crystal packing. In the structure of (I), the surfaces around the Sn-bound phenyl (C17–C22) and (C23–C28) rings are more concave than the equivalent rings participating in C—H⋯π inter­actions in (II), indicating their greater influence upon packing, as seen in the shorter H⋯ring centroid separations, Tables 2 ▸ and 3 ▸. This observation is also apparent from the Hirshfeld surfaces mapped over electrostatic potential corresponding to C⋯H contacts for (I) and (II), both showing red spots in the images of Fig. 6 ▸ correlating with their functioning as π-bond acceptors. The concave appearance of the Hirshfeld surface mapped over electrostatic potential around the Sn-bound phenyl ring (C14–C19) in the structure of (II) is indicative of its participation in two C—H⋯ π inter­actions, i.e. with the H13 and H23 hydrogen atoms. The other C—H⋯π contact involves methyl-H7C atom as the donor and phenyl (C8–C13) ring as the acceptor. The shape-indexed Hirshfeld surfaces highlighting the C—H⋯π contacts are shown in Fig. 7 ▸.

Views of Hirshfeld surfaces mapped over shape-index (a) for (I) and (b) for (II). The different C—H⋯π contacts are labelled and indicated as dashed lines.

The overall two-dimensional fingerprint plots for (I) and (II) and those delineated into H⋯H, C⋯H/H⋯C and S⋯H/H⋯S contacts (McKinnon et al., 2007 ▸) are illustrated in Fig. 8 ▸ a–d, respectively; their relative contributions n class="Chemical">are summarized in Table 4 ▸. Although the distribution of points in the overall plots of (I) and (II) have almost same (d e, d i) ranges, i.e. between 1.2 and 2.6 Å, the densities and the areas of their distributions are different. It is evident from the data in Table 4 ▸ and the fingerprint plot delineated into H⋯H contacts in Fig. 8 ▸ b that these contacts make the most significant contribution to the Hirshfeld surfaces of both (I) and (II). In the fingerprint plot of (I) delineated into H⋯H contacts (Fig. 8 ▸ b), all the points are situated at the (d e, d i) distances greater than or equal to their van der Waals separations i.e. 2 x 1.2 Å, hence there is no propensity to form such inter­molecular contacts. The peak at (d e, d i) distances slightly less than van der Waals separations in the fingerprint plot for (II) is due to a short inter­atomic H⋯H contact between symmetry-related meth­oxy- and di­thio­carbamate hydrogen atoms [H7A⋯H5A i = 2.36 Å; symmetry code: (i) −x, 2 − y, 1 − z]. In the fingerprint plot delineated into C⋯H/H⋯C contacts for (I), Fig. 8 ▸ c, the 32.9% contribution to the Hirshfeld surface and the symmetrical distribution of points showing bending of the pattern at (d e + d i)min ∼2.8 Å is the result of short inter­atomic C⋯H/H⋯C contacts [C1⋯H32ii = 2.85 and C14⋯H27iii = 2.84 Å; symmetry codes: (ii) 1 + x, y, z; (iii) 1 − x, 2 − y, −z]. In the structure of (II), a comparatively reduced contribution from these contacts to the surface is made, i.e. 24.4%, an observation ascribed to the presence of only C—H⋯π contacts in the mol­ecular packing, with no other short inter-atomic contacts. The negligible contribution from C⋯C contacts to the Hirshfeld surfaces indicate that despite the presence of three Sn-bound phenyl rings in the structures of both (I) and (II), and the presence of other two phenyl rings bound to the di­thio­carbamate ligand in (I), the structures show no significant π–π stacking. In the structure of (II), the presence of oxygen atoms does not have any significant influence on its mol­ecular packing although there is 4.7% contribution from O⋯H/H⋯O contacts to the Hirshfeld surface. The fingerprint plots delineated into S⋯H/H⋯S contacts for both the mol­ecules (I) and (II), Fig. 8 ▸ d, show that crowded geometries around the tin atoms prevent the sulfur atoms from forming such inter­molecular contacts although these contacts have significant contributions to their respective Hirshfeld surfaces, Table 4 ▸, as well as nearly symmetrical distributions of points in their plots. This observation was also noted in an earlier study describing related organotin di­thio­carbamate structures (Mohamad et al., 2016 ▸).

Database survey

According to a search of the Cambridge Structural Database (CSD; Groom et al., 2016 ▸), the di­thio­cn class="Chemical">arbamate ligands featuring in the present study have comparatively rare R/R′ substituents. For example, the −S2CN(Ben)CH2CH2Ph anion in (I) has only one precedent, namely in Pb[S2CN(Ben)CH2CH2Ph]2 (Sathiyaraj et al., 2012 ▸). There are eight examples of the −S2CN(CH2CH2OMe)2 anion, as in (II), being the focus of two recent systematic studies (Hogarth et al., 2009 ▸; Naeem et al., 2010 ▸).

Reflecting the inter­est in organon class="Chemical">tin di­thio­carbamates, there are approximately 40 examples of tri­phenyl­tin di­thio­carbamate structures in the CSD, all of which present the same basic structural motif as described herein for (I) and (II). The prototype compound, Ph3Sn(S2CNEt2) features the shortest Sn—S bond length of the series at 2.429 (3) Å (Hook et al., 1994 ▸). The most asymmetric mode of coordination of a di­thio­carbamate ligand, i.e. with Δ(Sn—S) of 0.74 Å, is found in the structure of Ph3Sn(4-nitro­phenyl­piperazine-1-di­thio­carbamate) (Rehman et al., 2009 ▸). On the other hand, the most symmetric mode of coordination is found in the structure of Ph3Sn(4-meth­oxy­phenyl­piperazine-1-di­thio­carbamate), having Δ(Sn—S) of 0.42 Å (Zia-ur-Rehman et al., 2011 ▸), i.e. the same value as found in the structure of (I) reported herein.

Synthesis and crystallization

Synthesis of (I): N-Benzyl-2-phenyl­ethyl­amine (2 mmol) dissolved in ethanol (10 ml) was stirred for 30 min in an ice-bath. 25% n class="Chemical">ammonia (1–2 ml) was added to generate a basic solution. After that, a cold ethano­lic solution of carbon di­sulfide (2 mmol) was added to the solution followed by stirring for about 2 h. Then, tri­phenyl­tin(IV) chloride (2 mmol) dissolved in ethanol (30 ml) was added drop wise into the solution followed by further stirring for 2 h. The precipitate that formed was filtered off and washed with cold ethanol a few times to remove impurities. Finally, the precipitate was dried in a desiccator. Recrystallization was achieved by dissolv­ing the compound in a chloro­form and ethanol mixture (1:1 v/v): this solution was allowed to slowly evaporate at room temperature yielding colourless slabs of (I). M.p.: 419–421 K. Yield: 85%. Analysis: found C, 64.5; H, 5.3; N, 2.3; S, 9.9. C34H31NS2Sn requires: C, 64.2; H, 4.9; N, 2.2; S, 10.1. IR (cm−1): 1476 ν(C—N), 1021 ν(C—S), 502 ν(Sn—C), 448 ν(Sn—S). 1H NMR (CDCl3): 7.44–7.86 (15H, Sn—Ph), 7.16–7.39 (10H, C-Ph), 5.03 (2H, CH2Ben), 3.96 (2H, NCH 2CH2), 3.04 (2H, NCH2CH 2). 13C{1H} NMR (CDCl3): δ 197.8 (S2C), 126.7–142.3 (Ar), 59.8 (CH2Ben), 56.4 (NCH2CH2), 32.8 (NCH2 CH2). 119Sn{1H} NMR (CDCl3): −180.2.

Compound (II) was prepared in essentially the same manner as for (I) but using bis­(2-meth­oxy­eth­yl)amine (5 mmol) in place of N-benzyl-2-phenyl­ethyl­amine. Recrystallization was from chloro­form solution to yield colourless slabs. M.p.: 366–367 K. Yield: 89%. Analysis: found C, 54.4; H, 4.4; N, 2.9; S, 12.1.

Refinement

Crystal data, data collection and structure refinement details are summn class="Chemical">arized in Table 5 ▸. Carbon-bound H atoms were placed in calculated positions (C—H = 0.95–0.99 Å) and were included in the refinement in the riding-model approximation, with U iso(H) set to 1.2–1.5U eq(C). In the refinement of (II), disorder was noted in the C5-chain of the di­thio­carbamate ligand. Specifically, the C6 and O2 atoms were modelled over two positions in the ratio 0.569 (2):0.431 (2). The anisotropic displacement parameters for both components of the C6 and O5 atoms were constrained to be equivalent; further, those for the C6 atoms were restrained to be approximately isotropic. The 1,2 and 1,3 bond lengths of the disordered residual were restrained to be similar to those of the ordered arm of the di­thio­carbamate ligand.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
