Crystal structure of cis-[1,2-bis-(di-phenyl-phosphan-yl)ethene-?2P,P']di-chlorido-platinum(II) chloro-form disolvate: a new polymorph.

ABSTRACT: The title compound, [PtCl2(C26H22P2)]·2CHCl3 (I), is the third monoclinic polymorph of this platinum(II) complex involving the bidentate ligand cis-1,2-bis-(di-phenyl-phosphan-yl)ethyl-ene (cis-dppe) [for the others, see: Oberhauser et al. (1998a ?). Inorg. Chim. Acta, 274, 143-154, and Oberhauser et al. (1995 ?). Inorg. Chim. Acta, 238, 35-43]. The structure of compound (I) was solved in the space group P21/c, with one complex mol-ecule in the asymmetric unit along with two solvate chloro-form mol-ecules. The PtII atom is ligated by two P and two Cl atoms in the equatorial plane and has a perfect square-planar coordination sphere. In the crystal, the complex mol-ecule is linked to the chloro-form solvate mol-ecules by C-H?Cl hydrogen bonds and face-on C-Cl?? inter-actions. There are also weak offset ?-? inter-actions present [inter-centroid distances are 3.770?(6) and 4.096?(6)?Å], linking the mol-ecules to form supra-molecular sheets that lie in the bc plane.
