The ligand HSC6H4PPh2 (0.029 g, 0.1 mmol) was added to a dichloromethane solution (20 ml) of [Au(C6F5)3(tht)] (0.079 g, 0.1 mmol). After stirring for 3 h, the solution was filtered through diatomaceous earth and concentrated in vacuo; addition of hexane precipitates the product as a white solid (yield: 47%). 1H NMR: δ(SH) 3.74(s). 31P{1H} NMR: δ 17.7 (s). 19F NMR: δ -118.0 (m, 4 F, Fo), -121.6 (m, 2 F, Fo), -157.1 (t, 3JFpFm = 19.7 Hz, 1 F, Fp), -157.3 (t, 3JFpFm = 19.9 Hz, 2 F, Fp), -161.1 (m, 4 F, Fm), -161.3 (m, 2 F, Fm). Crystals of the complex were obtained by slow diffusion of hexane into a dichloromethane solution.
The dichloromethane molecule is disordered over two sites with occupation factors 0.727 (9) and 0.273 (9). The minor Cl component and both C components were refined isotropically. The H atom of the thiol group was tentatively identified as a peak of 0.4 e Å-3 with acceptable geometry at sulfur, and was refined with a distance restraint (DFIX) of S—H = 1.33 (2) Å and fixed U. It however makes a short contact of 2.35 Å to C54 of a neighbouring molecule at 1 - x, 1 - y, 1 - z. Clearly this H-atom site should be interpreted with caution. We have previously failed to locate the H atom of SH groups in some gold complexes, even with apparently good data (Vicente et al., 1994). Other H atoms were included using a riding model. To improve stability of refinement, an extensive system of restraints to light-atom displacement parameter components and local ring symmetry was employed. Details are given in the final instruction file, which is included in the deposited material.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. ============================================================================== Dimensions not listed below: 3.5936 (0.0023) Au - S 1.3308 (0.0191) S - H0 99.85 (2.52) C42 - S - H0 ============================================================================== Least-squares planes (x,y,z in crystal coordinates) and deviations from them (* indicates atom used to define plane) - 2.6568 (0.0111) x + 5.1486 (0.0187) y + 12.5978 (0.0151) z = 3.7281 (0.0042) * 0.0215 (0.0016) Au * -0.0880 (0.0017) P * 0.0902 (0.0022) C11 * -0.1131 (0.0022) C21 * 0.0894 (0.0022) C31 Rms deviation of fitted atoms = 0.0862 ============================================================================== |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

In recent years, there has been considerable interest in thiolate–gold chemistry; most of the complexes studied have also contained phosphine ligands (Terroba et al., 1998; Cerrada et al., 1995; Gimeno et al., 1994; Yip et al., 1994; Davila et al., 1993; Nakamoto et al., 1993). Another way of combining the aspects of both thiolate and phosphine chemistry is to work with bidentate ligands containing both S and P functions, as are found in phosphinethiols. The selective coordination of either phosphorus or sulfur to different metal centres can in principle allow the combination of disparate metals in the same molecule. Such heteropolynuclear compounds are of interest because of their possible application in catalysis (Simpson & Colehamilton, 1996; Stephan, 1989).
The reaction of the ligand 2-(diphenylphosphino)thiophenol (Block et al., 1989) with [Au(C6F5)3(tht)] (Usón et al., 1982) proceeds with substitution of tetrahydrothiophene (tht), a labile ligand in gold chemistry, by the phosphine function of the ligand. The product obtained is the title compound, [Au(C6F5)3(PPh2C6H4SH)], (I), still containing the unchanged thiol group, which is a potential site for further reactions.
The structure of (1) is shown in Fig. 1. The gold centre displays square-planar geometry, with bond angles (Table 1) close to the ideal values. The mean deviation of gold and its four immediate donors from their best plane is 0.09 Å, whereby the atoms P and C21 lie on one side of the plane and C11 and C31 on the other. The Au—P distance, 2.3884 (16) Å, is amongst the longest so far observed in gold(III) complexes. This lengthening can reasonably be attributed to the trans effect of the pentafluorophenyl group. A search of the Cambridge Structural Database (Version of October 1998; Allen & Kennard, 1993) indeed revealed that the longest AuIII—P bonds are formed trans to σ-carbon ligands: e.g. cis-[Au(CH3)2(PPh3)(OPh)] 2.402 (4) Å (Sone et al., 1991); cis-[Au(CH3)2{Ph2P(O)CH2PPh2}Cl] 2.389 (2) Å (Paul & Schmidbaur, 1996); [Au(2-PhNNC6H4){3,4,5-(CH3O)3—C6H2COCH2}(PPh3)Cl] 2.386 and 2.390 (2) Å (Vicente et al., 1993). Typical examples without such ligands are [Au(C6F5)(S2C6H4)PPh3] 2.340 (1) Å (Cerrada et al., 1995); [AuCl3(PPh3)] 2.335 (4) Å (Bandoli et al., 1973); [AuMe3(PPh3)] 2.350 (6) and 2.347 (6) Å (Stein et al., 1981); [Au(SC6H4PPh2)2]BPh4 2.325 (4) and 2.332 (4) Å (Dilworth et al., 1994). The Au—C bond lengths, 2.056 (5)–2.073 (5) Å, are similar to those of other tris(pentafluorophenyl)gold(III) complexes: [Au(C6F5)3(S2C—PEt3)] 2.037 (3) and 2.076 (4) Å (Usón et al., 1987); [(µ-S2C—PEt3){Au(C6F5)3}2] 2.048 (16) and 2.090 (13) Å (Usón et al., 1987); NBu4[{Au(C6F5)3PPh2CHPh2}2Au] 2.057 (8) and 2.080 (8) Å (Fernández et al., 1995). The shortest Au—C distance (although the differences are not great) corresponds to the pentafluorophenyl group trans to phosphorus.
The intramolecular Au···S contact is 3.594 (2) Å, which represents at best a very weak interaction; such axial contacts are typical of AuIII complexes.
