title: Chlorido{[2-(dicyclo-hexyl-phosphano-yl)eth-yl]bis-[2-(dicyclo-hexyl-phosphan-yl)eth-yl]phosphane}platinum(II) chloride dichloro-methane hemisolvate tetra-hydrate.
abstract: The title compound, [PtCl(C(42)H(78)OP(4))]Cl·0.5CH(2)Cl(2)·4H(2)O, crystallizes as a contact ion-pair with two close inter-molecular C-H⋯Cl(-) contacts between CH acidic αH atoms of the phosphane ligand and the chloride anion. A chloride ligand together with three coordinating P ligand atoms create a slightly distorted square-planar coordination environment around the Pt(II) center. An inter-molecular water O-H⋯Cl(-) and water O-H⋯OP hydrogen-bond network completes the coordination around the anion. In addition, a disordered CH(2)Cl(2) solvent mol-ecule cocrystallized within a hydro-phobic cavity spanned by the dicyclo-hexyl-phosphane ligands.
