(Received 6 July 2010; accepted 22 July 2010; online 31 July 2010)

In the title compound, [Au(C4H12P2S2)2](CF3SO3), the gold(I) atom is tightly bonded to two S atoms belonging to different ligand mol­ecules and forms two weaker contacts to the remaining S atoms. The coordination geometry around gold is inter­mediate between linear-dicoordinate and tetra­hedral with an S—Au—S angle of 161.49 (3)°.

Comment top

Complexes of the group 11 metals with bidentate diphosphine disulfides (2L) have so far only encompassed the lighter elements Cu and Ag (Liu et al., 2003) which readily yield [M(2L)2]+ cations. Gold complexes have not been investigated, despite the interesting results the combination of these bidentate ligands with the propensity for AuI to form linear-dicoordinate complexes could produce.

The title compound shown in Figure 1 exhibits a structure that is intermediate between classic linear-dicoordinate and tetrahedral coordination. AuI thus forms a complex of the same stoichiometry as its lighter group elements, but with a significantly different geometry. It can be envisaged as a tetrahedron formed by the sulfur donor atoms in which the gold is displaced from the centre towards an edge. The metal is coordinated by two sulfur atoms of different ligands yielding short Au—S bonds [2.3099 (7) and 2.3044 (7) Å] and is further associated with the other sulfur atoms through Au···S contacts [3.3939 (8) and 3.2472 (8) Å]. The attractive nature of these contacts is demonstrated by the S—Au—S angle of 161.49 (3)° which significantly deviates from linearity.

In the molecular structure of the complex [Ag(C4H12P2S2)2]BF4 (Liu et al., 2003) the four Ag—S bonds are more uniform in length with distances between 2.534 (2) and 2.676 (2) Å. The replacement of silver by gold thus causes two of the four bonds to become significantly stronger while the other bonds are reduced to non-classical contacts. Au—S bonds in other phosphine sulfide complexes are significantly shorter than in the present structure, 2.277 (2) Å in [Au(SPPh3)2]PF2O2 (LeBlanc et al., 1997) and 2.281 (5) and 2.299 (5) Å in [1,1'-bis(diphenylthiophosphoryl)ferrocene]gold(I) tetrachloroaurate(III) (Gimeno et al., 2000), which can be attributed to the absence of additional stabilizing contacts in these structures.

The [Au(C4H12P2S2)2]+ cations in the crystal structure of the title compound are isolated and no intermolecular Au···Au or Au···S interactions are observed. The packing shown in Figure 2 is characterized by alternating layers of cations and anions parallel to the bc plane. The trifluoromethanesulfonate anion shows no disorder and exhibits low thermal movement.

Experimental top

A Schlenk vessel was charged with tetramethyldiphosphine disulfide (129 mg, 0.69 mmol), [AuCl(tht)] (tht = tetrahydrothiophene) (150 mg, 0.47 mmol) and sodium trifluoromethanesulfonate (86 mg, 0.50 mmol). Acetonitrile (20 ml) was added and the suspension stirred for 1 h and evaporated to dryness in vacuo. The residue was suspended in acetonitrile (20 ml), filtered, concentrated to ca 7 ml and layered with diethyl ether. Crystals grown at 258 K were washed with toluene to remove co-precipitated amorphous solids.

Refinement top

All H atoms were positioned geometrically (C—H = 0.98 Å) and constrained to ride on their parent atoms; Uiso(H) values were set at 1.5 times Ueq(C).

The largest residual electron density peak of 1.10 e Å-3 is located 0.83 Å from Au1.

Special details top

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.

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 > 2σ(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.
