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

The title compound, [PtCl2(C13H11O2P)2]·CHCl3, has a rare PtCl2 bridging of two dibenzooxaphosphorine ligands through the metal atom. The PtII 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—H⋯Cl and C—H⋯O hydrogen bonds. The crystal structure is further stabilized by π–π interactions involving the benzene rings, with a centroid–centroid distance of 3.658 (8) Å.

Novel Heterocyclic P-Ligands: Synthesis and Application in Pt(II) Complexes

3-Diphenylphosphino-1,2,3,6-tetrahydro- and 1,2,3,4,5,6-hexahydro-phosphinines, as well as dibenzo[c,e][1,2]oxaphosphorines (L) were prepared and used in the synthesis of the corresponding cis chelate Pt(II) complexes and PtCl2L2 complexes, respectively. The latter family of compounds includes 7-membered ring Pt(II) complexes.
