Chlorido{[2-(dicyclo­hexyl­phosphano­yl)eth­yl]bis­[2-(dicyclo­hexyl­phosphan­yl)eth­yl]phosphane}platinum(II) chloride dichloro­methane hemisolvate tetra­hydrate

The title compound, [PtCl(C42H78OP4)]Cl·0.5CH2Cl2·4H2O, crystallizes as a contact ion-pair with two close inter­molecular 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 PtII center. An inter­molecular water O—H⋯Cl− and water O—H⋯OP hydrogen-bond network completes the coordination around the anion. In addition, a disordered CH2Cl2 solvent mol­ecule cocrystallized within a hydro­phobic cavity spanned by the dicyclo­hexyl­phosphane ligands

Bis(1-{bis­[2-(diphenyl­phosphino­yl)eth­yl]phosphan­yl}-2-(diphenyl­phosphan­yl)ethane)dinitratoplatinum(II) methanol tetra­solvate

In the title compound, [Pt(NO3)2(C42H42O2P4)2]·4CH3OH, the Pt atom positioned on a crystallographic centre of inversion. The two symmetry-equivalent nitrate anions are weakly coordinated to the PtII ion, creating, together with four P ligand atoms, a distorted octa­hedral coordination environment. In addition, several close C—H⋯O contacts between the nitrate O atoms and phenyl H atoms are found. Hydrogen bonds from two methanol solvent mol­ecules to one of the O—P groups complete the crystal structure
