The title complex, [Au₂(C₁₇H₁₁N)₂(C₁₂H₁₀P)]ClO₄·C₂H₃N, contains two Au^III atoms bridged by a diphenylphosphanide ligand. Each Au atom is in a square-planar environment coordinated by diphenylphosphanide and 2,6-diphenylpyridine ligands. There are weak π–π stacking interactions between neighbouring molecules (the interplanar separations between two neighbouring dpp units are 3.40 and 3.57 Å). The intramolecular Au⋯Au separation is 3.788 (5) Å. The crystal structure shows weak intermolecular C—H⋯O and C—H⋯N hydrogen bonds involving an O atom of the perchlorate counter-ion and the N atom of the acetonitrile solvent molecule, respectively.

Comment top

Recently, extensive investigations on the biological properties of gold(III) have been reported (Kui et al., 2006; Wong et al., 1998). The stability of metal compounds is usually enhanced by multidentate chelating ligands. Li and his co-workers have reported multinuclear gold complex of 2,6-diphenyl-Pyridine ligand (dpp) to generate a planar gold(III) moiety (Li et al., 2006). In this context, the title complex, (I), has been prepared and its crystal structure is reported here.

The title compound show gold(III) atoms bridged by diphenylphosphanide. Each Au atom is surrounded by one P atom from diphenylphosphanide ligand and two C atoms, one N atom from dpp in a square-planar geometry, the least-squares plane through Au^III and dpp has a mean deviation of 0.04 (3) Å. The intramolecular Au···Au contact of 3.788Å is beyond a normal range of metal-metal interactions for d⁸ metal ions (3.09–3.50 Å) (Yam et al., 2002; Goshe et al., 2003; Lu et al., 2004). The Au–N(pyridyl) distances (2.027 (3), 2.041 (3) Å) are comparable to the related distances found in [Au(dpp)L]ⁿ⁺ analogues (1.94–2.06 Å), The Au–C(phenyl) distances (2.091 (3)–2.113 (3) Å) are comparable to the related distances found in [Au(dpp)L]ⁿ⁺ analogues (2.06–2.13 Å) (Li et al., 2006). The interplanar separation between two neighbouring dpp molecules are 3.40 and 3.57Å (Fig. 2). The crystal packing shows weak intermolecular C-H..O and C-H···N hydrogen bonds with O atoms of perchlorate counter-ion and N atom of acetonitrile molecule respectively. (Fig. 3, Table 2).

Experimental top

A mixture of Au(dpp)Cl (0.092 g, 0.2 mmol) and diphenylphosphine (0.018 g, 0.1 mmol) in acetonitrile (30 ml) was stirred for 2 h. Excess LiClO₄ was then added to yield a yellow precipitate, which was filtered, washed with diethyl ether. The precipitate was redissolve in acetonitrile. Yellow crystals suitable for X-ray diffraction were formed by vapour diffusion of diethyl ethyl ether into acetonitrile solution.

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 > 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.
