Abstract

The crystal structure of the title compound, [PtCl ₂(C ₂₅H ₂₂NPS)]·0.5CH ₂Cl ₂, was determined to establish the coordination properties of the (phosphan-yl)benzyl- idene-methanamine ligand to platinum. In the unit cell two mol-ecules of cis-[PtCl ₂(C ₂₅H ₂₂NPS)] are accompanied by a dichloro-methane solvent mol-ecule. The square-planar Pt ²⁺ coordination sphere is slightly distorted with the bidentate ligand coordinated via the P and the amine N atoms, and the Cl atoms located cis at the two remaining coordination sites. Parts of the thiophene ring and the solvate molecule were modeled as disordered with occupancy ratios of 0.55 (2):0.45 (2) and 0.302 (10):0.198 (10), respectively. Weak C - H⋯Cl inter-actions stabilize the crystal packing.
