Dichloridobis(2-methoxy-dibenzo[c,e][1,2]oxaphospho-rine-P)platinum(II) trichloro-methane solvate

Abstract

The title compound, [PtCl2(C13H11O 2P)2]·CHCl3, has a rare PtCl2 bridging of two dibenzooxaphospho-rine ligands through the metal atom. The Pt II ion is in a slightly distorted square-planar environment. The trichloro-methane solvent mol-ecule shows rotational disorder (major occupancy is 0.75) and is placed near to the inversion centre at (1/2, 1/2, 0) in channels parallel to the a axis. The solvent mol-ecule is linked to the complex mol-ecule via inter-molecular bifurcated C - H⋯Cl and C - H⋯O hydrogen bonds. The crystal structure is further stabilized by π-π inter-actions involving the benzene rings, with a centroid-centroid distance of 3.658 (8) Å.
