A non-solvated form of [(Z)-O-methyl-N-(2-methyl-phen-yl)-thio-carbamato-κS](tri-phenyl-phosphane-κP)gold(I): crystal structure and Hirshfeld surface analysis.

The title compound, [Au(C9H10NOS)(C18H15P)], features a near linear P-Au-S arrangement defined by phosphane P and thiol-ate S atoms with the minor distortion from the ideal [P-Au-S is 177.61 (2)°] being traced in part to the close intra-molecular approach of an O atom [Au⋯O = 3.040 (2) Å]. The packing features supra-molecular layers lying parallel to (011) sustained by a combination of C-H⋯π and π-π [inter-centroid distance = 3.8033 (17) Å] inter-actions. The mol-ecular structure and packing are compared with those determined for a previously reported hemi-methanol solvate [Kuan et al. (2008 ▸). CrystEngComm, 10, 548-564]. Relatively minor differences are noted in the conformations of the rings in the Au-containing mol-ecules. A Hirshfeld surface analysis confirms the similarity in the packing with the most notable differences relating to the formation of C-H⋯S contacts between the constituents of the solvate.

Chemical context

Triorganophosphanegold(I) carbonimido­thio­ates, i.e. mol­ecules of the general formula R 3PAu[SC(OR′)=NR′′ for R, R′ and R′′ = alkyl, aryl, were first described in 1993 as were the crystal and mol­ecular structures of archetypal Ph3PAu[SC(OMe)=NPh (Hall et al., 1993 ▸). Since then, approximately 70 crystal structures, including those of bident­ate phosphanes and bipodal analogues, have been described in the crystallographic literature (Groom et al., 2016 ▸). The inter­est in phosphanegold(I) carbonimido­thio­ates stems from two distinct considerations related to their relatively facile synthesis, their long-term stability and their readiness to crystallize, namely crystal engineering and evaluation for biological activity. In the former and reflecting their propensity to form diffraction-quality crystals, an unprecedented comprehensive series of compounds, R 3PAu[SC(OMe)=NC6H4NO2-p] (R = Et, Cy and Ph), and bidentate phosphane analogues, Ph2P–(CH2)–PPh2 for n = 1–4 and for when the bridge is ferrocenyl, enabled correlations between the formation of Au⋯Au (aurophilic) inter­actions and solid-state luminescence responses (Ho et al., 2006 ▸). In another series of compounds where the diphosphane ligand was held constant, i.e. [(Ph2P(CH2)4PPh2){AuSC(OR′)=NC6H4 Y-p}2] for R′ = Me, Et or iPr and Y = H, NO2 or Me, the packing was assessed in terms of delineating the influence of R′ and Y substituents (Ho & Tiekink, 2007 ▸). In yet another systematic series of compounds, i.e. of the general formula R 3PAu[SC(OMe)=NR′′], for R = Ph, o-tol, m-tol or p-tol, and R′′ = Ph, o-tol, m-tol, p-tol or C6H4NO2-p, it was possible to assess the impact of steric and electronic effects upon the formation of intra­molecular Au⋯O or Au⋯π(N-bound ring) inter­actions (Kuan et al., 2008 ▸). Over and above these studies, phosphanegold(I) carbonimido­thio­ates exhibit promising biological potential in the context of anti-cancer activity (Yeo, Ooi et al., 2013 ▸; Ooi et al., 2015 ▸) and anti-microbial activity (Yeo, Sim et al., 2013 ▸). Just as systematic variations in the substituents influences the mol­ecular packing, this also influences biological effects so that, for example, different apoptotic mechanisms of cell death are induced when the O-bound R′ is varied. It was in fact during biological investigations that the title compound, Ph3PAu[SC(OMe)=N(o-tol)] (I), was prepared once again, having been previously characterized as a 1:1 hemi-methanol solvate (I·0.5MeOH; Kuan et al., 2008 ▸). Herein, the crystal and mol­ecular structures of (I) are described along with Hirshfeld surface analyses of both (I) and (I·0.5MeOH).

Structural commentary

The gold(I) atom in (I), Fig. 1 ▸, exists within the anti­cipated linear geometry defined by thiol­ate-n class="Chemical">S1 and phosphane-P1 atoms. Support for the ‘thiol­ate-S1’ assignment comes about by the elongation of the C1—S1 bond to 1.768 (3) Å, Table 1 ▸, c.f. 1.6700 (14) Å, and contraction of the C1—N1 bond in (I) to 1.260 (3) Å, c.f. 1.3350 (15) Å in the structure of the non-coordinating mol­ecule, i.e. S=C(OMe)N(H)(o-tol) (Kuan et al., 2005 ▸). The small deviation from linearity about the gold(I) atom [P—Au—S = 177.61 (2)°] may be related to the close approach of the O1 atom, Au⋯O1 is 3.040 (2)°, as the carbonimido­thio­ate ligand is orientated to place the oxygen atom in close proximity to the gold atom, Fig. 1 ▸. There are also significant differences in key angles between the coordinating and non-coordinating forms of the ligand, especially about the C1 atom. These reflect the reorganization of π-electron density manifested in the C=N and C=S bonds, respectively. Thus, the widest angles in the anion involve C=N and those in the free mol­ecule, involve C=S. A relatively large change is noted for the C1—N1—C2 angles, i.e. 121.4 (2) and 127.11 (12)°, respectively, for the coordinating and non-coord­inating ligands, which is a result of the presence of the acidic proton in the latter. In terms of conformation of the anion in (I), the central residue comprising the S1, O1, N1 and C1 atom is strictly planar (r.m.s. deviation of the fitted atoms = 0.0091 Å), with the pendent C2 and C9 atoms lying 0.035 (4) and 0.198 (4) Å out of this plane, respectively. The dihedral angle between the central residue and the N-bound aryl ring is 85.08 (7)°, indicating a nearly perpendicular arrangement; in the free ligand the comparable angle is 51.84 (6)° (Kuan et al., 2005 ▸).

Note: (a) Kuan et al. (2008 ▸).

Salient geometric parameters for (I·0.5MeOH) (Kuan et al., 2008 ▸) are also included in Table 1 ▸. From these data, it is apparent there are no great variations between the structures with perhaps the exception of the n class="Chemical">Au—S1 bond length in (I) being 0.01 Å longer than in (I·0.5MeOH). In terms of angles, the angle subtended at the S1 atom is about 2° tighter in (I). The intra­molecular Au⋯O1 separation is 0.05 Å shorter in (I) but the deviation from linearity is less, reflecting the weak nature of this inter­action.

Fig. 2 ▸ shows an overlay diagram for (I) and I in (I·0.5MeOH). From this it can be seen there is evidently a close overlap of all but the aryl rings that display orientational differences.

Supra­molecular features

In the crystal of (I), the most prominent points of contact between mol­ecules are of the type C—H⋯π and π–π, Table 2 ▸. Thus, centrosymmetrically related o-tolyl residues associate via pairs of methyl-C—H⋯π(o-tol) inter­actions, and centrosymmetrically related n class="Chemical">phosphane ligands are connected via face-to-face π–π inter­actions involving one of the P-bound phenyl rings only. The result is the formation of supra­molecular layers lying parallel to (011) as illustrated in Fig. 3 ▸ a. The layers stack with no directional inter­actions between them, Fig. 3 ▸ b.

The packing of (I·0.5MeOH) is also characterized by supra­molecular layers. These are sustained by π–π inter­actions of 3.687 (4) Å between centrosymmetrically related mol­ecules in a face-to-face fashion, as for (I), and by phenyl- and o-n class="Chemical">tolyl-C—H⋯π(P-phen­yl) inter­actions. The layers stack along the b axis devoid of specific inter­actions between successive layers. This arrangement defines columns along the a axis in which reside the disordered methanol mol­ecules, Fig. 4 ▸. The partially occupied methanol mol­ecules in (I·0.5MeOH), disordered over a centre of inversion, are connected to the host framework via methyl-C—H⋯S inter­actions.

Analysis of the Hirshfeld surfaces

Hirshfeld surface analysis and fingerprint plots were undertaken to study the inter­molecular contacts and topological differences between (I) and its methanol hemi-solvate, (I·0.5n class="Chemical">MeOH). Briefly, the inter­nal (d i) and external (d e) distances of atomic surface points to the nearest nucleus were computed for the mol­ecules in both (I) and (I·0.5MeOH) (Spackman & Jayatilaka, 2009 ▸; McKinnon et al., 2007 ▸). The resulting normalized contact distances (d norm) were mapped on the Hirshfeld surface in the range −1.04 to 1.91 Å. The contact distances shorter than the sum of van der Waals radii are highlighted in red while distances equal to or longer than the sum of van der Waals radii are shown in white and blue, respectively (McKinnon et al., 2007 ▸). The combination of d i and d e in inter­vals of 0.01 Å result in the two-dimensional fingerprint plots, where the different colours on the fingerprint plots represent the probability of occurrence, ranging from blue (few points) through green to red (many points) (Spackman & McKinnon, 2002 ▸). All analyses were performed using Crystal Explorer (Wolff et al., 2012 ▸).

The number of Hirshfeld surfaces that are unique in a given crystal structure depends on the number of independent mol­ecules in the asymmetric unit (Fabbiani et al., 2007 ▸). For this reason, the Hirshfeld surfaces for (I·0.5MeOH) were modelled separately for (I) and for n class="Chemical">MeOH, while the Hirshfeld surface of (I·0.5MeOH), as a whole, were also included for a thorough comparison of the mol­ecular packing in (I) and (I·0.5MeOH).

Fig. 5 ▸ a and 5b show the front and back views of Hirshfeld surfaces for (I), (I·0.5MeOH) as well as for I in (I·0.5n class="Chemical">MeOH) which are displayed in approximately the same orientation. Despite the presence of additional solvent mol­ecule in (I·0.5MeOH), both this and (I) are governed by similar inter­molecular contacts as can be observed through the appearance of several red spots on the Hirshfeld surfaces of both structures. These are mainly attributed to H⋯H, C⋯H/H⋯C and S⋯H/H⋯S contacts. However, a close inspection of the Hirshfeld surface of I in (I·0.5MeOH) reveals a stark difference as compared to (I), in that evidence is found for a close contact through a S⋯H inter­action with the solvent MeOH mol­ecule as readily seen from the intense red spot in Fig. 5 ▸ a – right. Apart from this contact, I in (I·0.5MeOH) also forms weak inter­action, as demonstrated by the less intense red spot in Fig. 5 ▸ b – right, through O⋯H with another mol­ecule of I but beyond the sum of their van der Waals radii (Spek, 2009 ▸).

In view that the conformational flexibility highlighted in Fig. 2 ▸, the mapping of curvedness over the Hirshfeld surface was undertaken in order to correlate these with some physico­chemical properties. Fig. 5 ▸ c and 5d show the front and back views of the curvedness for (I), (I·0.5MeOH) and I in (I·0.5n class="Chemical">MeOH). From these views, it is clear (I) exhibits a relatively broad region of curvedness surface, Fig. 5 ▸ c – left. It is presumably for this reason that (I) has a relatively greater surface area, indicating a more compact conformation, i.e. having a lower volume, and is more densely packed than I in (I·0.5MeOH), see data in Table 3 ▸. Inter­estingly, it seems the mol­ecular shape exerts a great influence over the inter­molecular inter­actions and the density of the resultant crystal structures, Table 3 ▸. The packing efficiency of (I) is also greater than that of (I·0.5MeOH), suggesting that the incorporation of methanol in the mol­ecular packing of (I·0.5MeOH) is not directed by the need to fill otherwise free space in (I).

The complete two-dimensional fingerprint plots for (I), (I·0.5MeOH) and, for additional comparison, I in (I·0.5n class="Chemical">MeOH), along with the decomposed two-dimensional plots for the indicated inter­actions are presented in Fig. 6 ▸, while the percentage contributions are represented graphically in Fig. 7 ▸. As mentioned previously, mol­ecules of (I) in its unsolvated and solvated forms are governed by similar inter­molecular close contacts which mainly comprise non-hydrogen-bond inter­actions. Specifically, H⋯H, being the most dominant inter­action among all, ca 57.3% in (I) and 55.4% in (I·0.5MeOH), forms a forceps-like fingerprint in (I), by contrast to the distinctive spike of (I·0.5MeOH), Fig. 6 ▸ b. It is noted there is not much to distinguish the fingerprint patterns due to C⋯H/H⋯C, Fig. 6 ▸ c. This observation is vindicated by the near equivalence of the sums of the d e + d i distances of ∼2.70 Å for (I) and ∼2.64 Å for (I·0.5MeOH) and with the relative contributions of approximately 23.3 and 23.8% to the overall surface areas, respectively. However, a marked difference is observed in the corresponding pincers-like fingerprint plots due to S⋯H/H⋯S interactions, Fig. 6 ▸ d. Thus, the plot for (I) displays a sum of inter­molecular contact distance d e + d i of ∼2.88 Å, originating from weak phenyl-C–H⋯S contacts. For the solvate, a mixed inter­action mode is evident from the asymmetric fingerprint plot indicating inter­actions between two chemically and crystallographically distinct mol­ecules, i.e. the relatively strong solvent⋯solute methyl-C—H⋯S inter­action with the sum of d e + d i distances being ∼2.42 Å coupled with a weak meth­oxy-C—H⋯S contact with d e + d i = ∼3.1 Å. Such inter­actions contribute roughly 3.2% (S⋯H–solvent) and 1.1% (S⋯H–meth­oxy) to the total 4.3% to the overall Hirshfeld surface of I in (I·0.5MeOH) compared to a ∼7.5% contribution in (I). Mol­ecule (I) does not forms any meaningful contacts through O⋯H/H⋯O owing to their long contact distances despite these contacts constituting approximately 2.4% of the overall contacts on the Hirshfeld surface, Fig. 6 ▸ e. Upon crystallization with methanol solvent, the overall contribution increases to 6.4% with the sum of d e + d i of ∼2.50 Å which is considered longer than typical O⋯H inter­actions with distances of ∼2.14 Å (Gavezzotti, 2016 ▸).

Database survey

As mentioned in the Chemical context, there are over 70 mol­ecular structures in the crystallographic literature (Groom et al., 2016 ▸) based on the general formula R 3PAu[SC(OR′)=NR′′ for R, R′ and R′′ = alkyl, aryl. The present structural pair, (I) and (I·0.5n class="Chemical">MeOH) represents the second example of solvatomorphism, with the prototype compound Ph3PAu[SC(OMe)=NPh (Hall et al., 1993 ▸) being also found in a chloro­form solvate (Kuan et al., 2008 ▸). The common feature of all four mol­ecules is the presence of intra­molecular Au⋯O inter­actions. Very recently, a polymorph of Ph3PAu[SC(OEt)=NPh has been reported (Yeo et al., 2016 ▸) in which there has been a dramatic conformational change compared with the previously described form (Hall & Tiekink, 1993 ▸). While the latter features the normally observed Au⋯O inter­action, the new form features intra­molecular Au⋯π (Caracelli et al., 2013 ▸) inter­actions. It was suggested that the crystallization conditions determined the conformation with that featuring the Au⋯π inter­actions being the thermodynamic outcome (Yeo et al., 2015 ▸, 2016 ▸).

Synthesis and crystallization

IR spectra were obtained on a Perkin–Elmer Spectrum 400 FT Mid-IR/Far-IR spectrophotometer from 4000 to 400 cm−1; abbreviation: s, strong. The 1H NMR spectrum was recorded in n class="Chemical">CDCl3 on a Bruker Avance 400 MHz NMR spectrometer with chemical shifts relative to tetra­methyl­silane; abbreviations for NMR assignments: s, singlet; d, doublet; t, triplet; m, multiplet.

Preparation of (I) NaOH (Merck; 0.20 mmol, 0.008 g) in MeOH (Merck; 1 ml) was added to a suspension of Ph3PAuCl (0.20 mmol, 0.100 g) in MeOH (Merck; 10 ml), followed by addition of the thio­carbamide, MeOC(=S)N(H)(o-tol) (0.20 mmol, 0.036 g), prepared following literature precedents (Ho et al., 2005 ▸), in MeOH (10 ml). The resulting mixture was stirred for 2 h at 323 K. The solution was left for slow evaporation at room temperature, yielding colourless blocks after 2 weeks. Yield: 0.109 g (85%). M.p. 389–391 K.

IR (cm−1): 1435 (s) (C=N), 1132 (s) (C—O), 1100 (s) (C—S). 1H NMR (400 MHz, CDCl3, 298 K): δ 7.53–7.39 (m, br, 15H, Ph3P), 6.86 (d, 1H, o-tol-H4, J = 6.24 Hz), 6.85 (t, 1H, o-tol-H3, J = 6.16 Hz), 6.73 (d, 1H, o-tol-H1, J = 7.70 Hz), 6.54 (t, 1H, o-tol-H2, J = 7.16 Hz), 3.93 (s, 3H, OMe), 2.11 (s, 3H, o-tol-Me) p.p.m.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 4 ▸. The carbon-bound n class="Disease">H atoms were placed in calculated positions (C—H = 0.95–0.98 Å) and were included in the refinement in the riding-model approximation, with U iso(H) set to 1.2–1.5U equiv(C). Owing to poor agreement, a number of reflections, i.e. (0 4), (9 5), ( 3 12), ( 7), ( 11 2), ( 10 1), ( 4), (7 6), ( 9), (4 2), ( 14), ( 15), (6 7) and (5 8 5), were omitted from the final cycles of refinement. The maximum and minimum residual electron density peaks of 0.97 and 1.14 e Å−3, respectively, were located 0.80 and 0.85 Å from the Au atom.

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.
