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.

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.

Bis(1-{bis-[2-(diphenyl-phosphino-yl)eth-yl]phosphan-yl}-2-(diphenyl-phosphan-yl)ethane)dinitratoplatinum(II) methanol tetra-solvate.

In the title compound, [Pt(NO(3))(2)(C(42)H(42)O(2)P(4))(2)]·4CH(3)OH, the Pt atom positioned on a crystallographic centre of inversion. The two symmetry-equivalent nitrate anions are weakly coordinated to the Pt(II) ion, creating, together with four P ligand atoms, a distorted octa-hedral coordination environment. In addition, several close C-H⋯O contacts between the nitrate O atoms and phenyl H atoms are found.
