Dichloridobis(2-methoxydibenzo[c,e][1,2]oxaphosphorine-P)platinum(II) trichloromethane solvate

Abstract: The title compound, [PtCl₂(C₁₃H₁₁O₂P)₂]·CHCl₃, has a rare PtCl₂ bridging of two dibenzooxaphosphorine ligands through the metal atom. The Pt^II ion is in a slightly distorted square-planar environment. The trichloromethane solvent molecule 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 molecule is linked to the complex molecule via intermolecular bifurcated C-HCl and C-HO hydrogen bonds. The crystal structure is further stabilized by [pi] - [pi] interactions involving the benzene rings, with a centroid-centroid distance of 3.658 (8) Å.
