Comment top

Binuclear complexes of gold with certain bidentate ligands are of interest owing to their rich luminescence and bonding properties (Jaw et al., 1989; Khan et al., 1988; King et al., 1989). In this context, several compounds of binuclear [Au2(µ-dppm)2]2+ have been characterized previously (Jaw et al., 1989; Khan et al., 1989; Porter et al., 1989; Liou et al., 1994; Wang et al., 1994; Bauer et al., 1997) counterbalanced by various anionic species. Herein, we described another crystal structure determination of the dication but isolated as the hexafluorophosphate salt, i.e. [Au2(µ-dppm)2](PF6)2·2CH2Cl2, (I) (Fig. 1 and Table 1).

The asymmetric unit of (I) comprises half a dication, [Au2(µ-dppm)2]2+, situated about a twofold axis of symmetry, two independent PF6 anions, each lying on Au gold atoms are doubly bridged by two dppm ligands. The Au center exists in the expected linear geometry with the P1—Au—P2 angle being 177.85 (13)°. The intramolecular Au···Au separation is 2.9792 (10) Å. The overall molecular geometry is in essential agreement with the previously determined structures cited above.

Experimental top

The title compound was synthesized by a modification of a literature procedure (Porter et al., 1989). The complex was obtained by the reaction between [Au2(µ-dppm)2]Cl2 and AgPF6 in a 1:2 ratio in acetonitrile solution under anaerobic conditions for 12 h. After the white precipitate, AgCl, was filtered off, the solution was evaporated under vacuum affording [Au2(µ-dppm)2](PF6)2 in good yield. Well formed colorless crystals suitable for X-ray diffraction measurements were grown by the slow diffusion of diethyl ether into a mixture of dichloromethane and a minimum of acetonitrile at room temperature.

Refinement top

The positions of the H atoms were generated geometrically (C—H bonds lengths were fixed at 0.96 Å), assigned isotropic displacement parameters and allowed to ride on their respective parent C atoms. The maximum (?) residual electron-density peak was located near the Au atom.

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.
