Crystal structure of (4,4'-bipyridyl-κN)bis-[N-(2-hydroxy-ethyl)-N-iso-propyl-dithio-carbamato-κ2S,S']zinc(II)-4,4'-bipyridyl (2/1) and its isostructural cadmium(II) analogue.

The title structures, [M(C6H12NOS2)2(C10H8N2)]·0.5C10H8N2, for M = Zn, (I), and Cd, (II), feature terminally bound 4,4'-bipyridyl ligands and non-coordinating 4,4'-bi-pyridyl mol-ecules, with the latter disposed about a centre of inversion. The coordination geometry about the metal atom is defined by two non-symmetrically chelating di-thio-carbamate ligands and a pyridyl N atom. The NS4 donor sets are distorted but, approximate to trigonal bipyramidal in each case. In the crystal, hy-droxy-O-H⋯O(hy-droxy) and hy-droxy-O-H⋯N(pyrid-yl) hydrogen bonds between the zinc-containing mol-ecules lead to a supra-molecular layer parallel to (100). The three-dimensional architecture arises as the layers are linked via methine-C-H⋯S, pyridyl-C-H⋯O(hy-droxy) and π-π [inter-centroid distance between coordinated pyridyl rings = 3.6246 (18) Å] inter-actions. Channels along the c-axis direction are occupied by the non-coordinating 4,4'-bipyridine mol-ecules, which are held in place by C-H⋯π(chelate ring) contacts.

Chemical context

The ditopic ligand 4,4′-bi­pyridyl is ubiquitous in coordination chemistry, usually providing bridges between metal centres to generate coordination n class="Chemical">polymers. While bidentate bridging is normally observed in the structural chemistry of zinc(II) bis­(N,N′-di­alkyl­dithio­carbamate)s, these more often than not lead to binuclear species of the general formula [Zn(S2CNRR′)2]2(4,4′-bipyrid­yl) as first observed in the archetypal compound [Zn(S2CNEt2)2]2(4,4′-bipyrid­yl) (Zem­skova et al., 1994 ▸) and in other compounds relevant to the present study, such as {Zn[S2CN(R)CH2CH2OH]2}2(4,4′-bipyrid­yl) for R = Me, Et and CH2CH2OH (Benson et al., 2007 ▸). The exceptional structure is that of Zn[S2CN(n-Pr)2]2(4,4′-bipyrid­yl), which features a relatively rare monodentate coordination mode for the 4,4′-bipyridyl mol­ecule (Klevtsova et al., 2001 ▸). The analogous chemistry for cadmium(II) bis(N,N′-di­alkyl­dithio­carbamate)s is considerably less explored with the only example in the Cambridge Structural Database (Groom et al., 2016 ▸) being a linear coordination polymer in the crystal of {Cd[S2CN(CH2Ph)2]2(4,4′-bipyrid­yl)} (Fan et al., 2007 ▸). The difference in chemistry between zinc and cadmium di­thio­carbamates can be rationalized in terms of the larger size of cadmium versus zinc but, also in terms of the reduced Lewis acidity of the zinc atom owing to the strong chelation mode of the di­thio­carbamate ligand. This is also true for cadmium whereby unusual coordination modes are found for related pyridyl-containing mol­ecules that might otherwise be expected to be bridging. This is discussed further below in Database survey. In the present report, the crystal and mol­ec­ular structures of two compounds, formulated as Zn[S2CN(i-Pr)CH2CH2OH]2(4,4′-bipyrid­yl)·0.5(4,4′-bipyrid­yl) (I) and the cadmium analogue (II), are described, i.e. featuring monodentate and non-coordinating 4,4′-bi­pyridine mol­ecules.

Structural commentary

The mol­ecular structure of the constituents of (I) are shown in Fig. 1 ▸ a and selected geometric parameters are collected in Table 1 ▸. The asymmetric unit comprises an entire mol­ecule of Zn[S2Cn class="Chemical">N(i-Pr)CH2CH2OH]2(4,4′-bipyrid­yl) and half a mol­ecule of 4,4′-bi­pyridine, the latter being disposed about a centre of inversion. The zinc atom is coordinated by two di­thio­carbamate ligands that form disparate Zn—S bond lengths. This is seen in the values of Δ(Zn—S) = Zn—Slong − Zn—Sshort, which compute to 0.19 and 0.23 Å for the S1- and S3-di­thio­carbamate ligands, respectively. The fifth position in the coordination geometry is occupied by a pyridyl-N atom. Based on the value of τ (Addison et al., 1984 ▸), which equals to 0.0 and 1.0 for ideal square-pyramidal and trigonal–bipyramidal geometries, respectively, it is possible to assign a coordination geometry based on the NS4 donor set. In (I), τ = 0.64 indicating a highly distorted coordination geometry but, one approximating a trigonal bipyramid. In this description, the less tightly bound S2 and S4 atoms define the axial positions, Table 1 ▸. The coordinated 4,4′-bipyridyl mol­ecule is non-planar with the dihedral angle between the two residues being 28.12 (14)°.

Crystals of (II) are isostructural to those of (I), Fig. 1 ▸ b and Table 2 ▸. Some differences in mol­ecular geometry are apparent, most notably in the degree of symmetry in the Cd—S bond lengths, i.e. Δ(n class="Chemical">Cd—S) = 0.09 and 0.11 Å for the S1- and S3-di­thio­carbamate ligands, respectively. This is reflected in the narrower ranges in the C—S bond lengths in (II) cf. (I), Tables 1 ▸ and 2 ▸. The value of τ = 0.67 suggests a coordination geometry marginally closer to trigonal bipyramidal in (II) than for (I). The dihedral angle between the two rings comprising the coordinated 4,4′-bipyridyl mol­ecule is 28.86 (7)°.

Supra­molecular features

The mol­ecular packing of (I) comprises conventional hydrogen bonding as well as a number of weaker, non-covalent inter­actions, Table 3 ▸. The presence of hy­droxy-O—H⋯O(hy­droxy) n class="Chemical">hydrogen bonds leads to the formation of a centrosymmetric, 28-membered {⋯HOC2NCSZnSCNC2O}2 synthon. This ring contains two additional hy­droxy-O—H H atoms and these form hy­droxy-O—H⋯N(pyrid­yl) hydrogen bonds with the non-coordinating end of the monodentate 4,4′-bipyridyl mol­ecules. This network of hydrogen bonds leads to the formation of a two-dimensional array lying parallel to (100), Fig. 2 ▸ a. These layers are connected into double-layers via methine-C—H⋯S and π–π inter­actions involving the coordinated pyridyl ring [inter-centroid distance between the (N3/C13–C17) and (N3/C13–C17)i rings = 3.6246 (18) Å and angle of inclination = 0.46 (13)° for symmetry code (i): −x, y,  − z]. The double-layers are connected into a three-dimensional architecture via 4,4′-bipyridyl-C—H⋯O(hy­droxy) inter­actions, involving an H atom from the non-coordinating ring of the coordinated 4,4′-bipyridyl mol­ecule. This architecture defines channels parallel to the c axis in which residue the non-coordinating 4,4′-bi­pyridine mol­ecules. The closest inter­action between the host and guests are of the type pyridine-C—H⋯π(Zn/S3/S4/C7), i.e. C—H⋯π(chelate ring), a supra­molecular synthon gaining prominence in the structural chemistry of metal-containing species (Tiekink, 2017 ▸), especially for di­thio­carbamates (Tiekink & Zukerman-Schpector, 2011 ▸) owing to the ability of the di­thio­carbamate ligand to form strong chelating inter­actions (see above).

Database survey

As mentioned in the Chemical context, ditopic ligands such as 4,4′-bipyridyl are normally observed providing bridges between metal centres. Thus, the structures of (I) and (II) are doubly curious as not only is the 4,4′-bipyridyl ligand coordinating in a monodentate fashion, there is a non-coordinating 4,4′-bi­n class="Chemical">pyridine mol­ecule in the crystal. Recent reports confirm these inter­esting observations with related bipyridyl-type mol­ecules of both the zinc(II) and, especially, cadmium(II) di­thio­carbamates. Thus, just as for the 4,4′-bipyridyl structures mentioned in the Chemical context, i.e. [Zn(S2CNEt2)2]2(4,4′-bipyrid­yl) (Zemskova et al., 1994 ▸) and Zn[S2CN(n-Pr)2]2(4,4′-bipyrid­yl) (Klevtsova et al., 2001 ▸), with the anti­cipated bidentate, bridging and non-anti­cipated terminal coordination, respectively, similar chemistry occurs for the ditopic ligand with an ethyl­ene space, i.e. trans-bis­(4-pyrid­yl)ethyl­ene (bpe) where structures of both bridging, i.e. [Zn(S2CNEt2)2]2(bpe) (Arman et al., 2009 ▸), and terminal, i.e. Zn[S2CN(n-Pr)2]2(bpe) (Lai & Tiekink, 2003 ▸), coordination modes are known. Very recently, terminal coordination was found for 4-pyridine­aldazine in the structure of Zn[S2CN(Me)CH2CH2OH2]2(4-pyridine­aldazine) (Broker et al., 2017 ▸). In the realm of cadmium di­thio­carbamates, the potentially bridging ligand just mentioned occurs in the structure of Cd[S2CN(n-Pr)CH2CH2OH2]2(4-pyridine­alda­zine)2 with both being terminally bound (Broker & Tiekink, 2011 ▸). The ditopic ligand bpe was mentioned above. In the case of cadmium di­thio­carbamates, a bidentate, bridging mode is seen in the crystal of [Cd(S2CNEt2)2(bpe)] (Chai et al., 2003 ▸). However, in another example both bridging and terminal modes, in a 1:2 ratio, are seen in the structure of Cd[S2CN(i-Pr)CH2CH2OH2]2(bpe)3 (Jotani et al., 2016 ▸). The occurrence of unusual coordination modes for these bipyridyl-type ligands indicate additional factors are coming into play, often a competition between hydrogen bonding and M←N donor inter­actions but, not always as seen in the structure of Zn[S2CN(n-Pr)2]2(4,4′-bipyrid­yl) (Klevtsova et al., 2001 ▸).

Synthesis and crystallization

All chemicals and solvents were used as purchased without purification·The melting point was determined using an Krüss KSP1N melting point meter. The IR spectra were obtained by the attenuated total reflectance (ATR) technique on a Perkin Elmer RX1 FTIR spectrophotometer from 4000 to 400 cm−1. n class="Chemical">1H and 13C NMR spectra were recorded at room temperature in DMSO-d 6 solution on a Bruker Avance 400MHz NMR spectrometer.

Synthesis of (I): 4,4′-bi­pyridine (1.79 mmol, 0.28 g) in n class="Chemical">ethanol (25 ml) was added dropwise to bis­(N-2-hy­droxy­ethyl,N-iso­propyl­dithio­carbamato)zinc(II) (1.21 mmol, 0.51 g) in ethanol (25 ml). The resulting mixture was stirred for 0.5 h follow by filtration. After a week of slow evaporation of the filtrate, yellow blocks precipitated (yield: 0.698 g, 88%; m.p. 445.6 K). IR (cm−1): 1467 (m) [ν(C—N)], 1175 (m) [ν(C—S)] cm−1. 1H NMR: δ 8.78–7.83 (m, 12H, aromatic H), 5.14 (sept, 2H, NCH, 6.63 Hz), 4.90 (t, 2H, OH, 5.38 Hz), 3.78–3.64 (m, 8H, NCH2CH2O), 1.18 (d, 12H, CH3, 6.72 Hz). 13C NMR: δ 204.15 (CS2), 150.53, 144.65, 121.58 (aromatic-C), 58.21 (CH2O), 55.53 (NCH2), 49.80 (NCH), 19.88 (CH3).

Synthesis of (II): 4,4′-bi­pyridine (1.61 mmol, 0.25 g) in n class="Chemical">ethanol (25 ml) was added dropwise to bis­(N-2-hy­droxy­ethyl,N-iso­propyl­dithio­carbamato)cadmium(II) (1.07 mmol, 0.50 g) in ethanol (25 ml). The resulting mixture was stirred for 0.5 h follow by filtration. A week of slow evaporation of the filtrate yielded yellow blocks (yield: 0.652 g, 87%; m.p. 438.7 K). IR (cm−1): 1467 (m) [ν(C—N)], 1174 (m) [ν(C—S)] cm−1. 1H NMR: δ 8.79–7.80 (m, 12H, aromatic H), 5.22 (sept, 2H, NCH, 6.63 Hz), 4.84 (t, 2H, OH, 5.52 Hz), 3.80–3.64 (m, 8H, NCH2CH2O), 1.17 (d, 12H, CH3, 6.72 Hz). 13C NMR: δ 205.29 (CS2), 150.57, 144.46, 121.41 (aromatic-C), 58.26 (CH2O), 56.62 (NCH2), 50.47 (NCH), 19.91 (CH3).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 5 ▸. For each of (I) and (II), carbon-bound n class="Disease">H atoms were placed in calculated positions (C—H = 0.95–1.00 Å) and were included in the refinement in the riding-model approximation, with U iso(H) set to 1.2–1.5U eq(C). The O-bound H atoms were located in difference-Fourier maps but were refined with a distance restraint of O—H = 0.84±0.01 Å, and with U iso(H) set to 1.5U eq(O). For (I), owing to poor agreement, two reflections, i.e. (0 0 6) and (27 3 4), were omitted from the final cycles of refinement. For (II), one reflection, i.e. ( 7 7), was omitted for the same reason.

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.
