Comment top

cis- and trans-Dimethylebis(triphenylarsine)platinum(II) are useful to prepare other platinum complexes. The structures of the cis-isomer have been not reported. During the course of our studies on platinium sulfide compounds cis-[Pt2Me4(µ-SMe2)2] with Lewis bases, a colorless crystals of the title compound, (I), was obtained. As shown in Fig.1, the platinum centre is four-coordinated and adopts a nearly square planar geometry. The Pt—As bond lengths (2.3960 (2) and 2.4086 (2) Å) and Pt—C bond lengths (2.060 (3) and 2.083 (3) Å), as well as the bond angles around the Pt atom are similar to those in the above-mentioned structures.

Experimental top

The title complex was prepared by the addition of an excess of AsPh3(0.2133 mmol) to an anhydrous diethyl ether solution (20 ml) of cis-[PtMe2(SMe2)2]2 (0.17413 mmol) (Puddephatt et al. 1998) at 298 K. The desired product precipitates spontaneously in near quantitative yield (78.9% yield) and was recrystallized from dichloromethane at 298 K to yield colourless prisms of (I).

Refinement top

Thelargest peak in the final difference electron density synthesis was 0.559 e-3 and the largest hole was -1.070 e-3 with an RMS deviation of 0.104 e-3.

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.
