Chlorido{[2-(dicycloÂhexylÂphosphanoÂyl)ethÂyl]bisÂ[2-(dicycloÂhexylÂphosphanÂyl)ethÂyl]phosphane}platinum(II) chloride dichloroÂmethane hemisolvate tetraÂhydrate
The title compound, [PtCl(C42H78OP4)]Cl·0.5CH2Cl2·4H2O, crystallizes as a contact ion-pair with two close interÂmolecular 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 interÂmolecular water O—H⋯Cl− and water O—H⋯OP hydrogen-bond network completes the coordination around the anion. In addition, a disordered CH2Cl2 solvent molÂecule cocrystallized within a hydroÂphobic cavity spanned by the dicycloÂhexylÂphosphane ligands
Bis(1-{bisÂ[2-(diphenylÂphosphinoÂyl)ethÂyl]phosphanÂyl}-2-(diphenylÂphosphanÂyl)ethane)dinitratoplatinum(II) methanol tetraÂsolvate
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 octaÂhedral 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 molÂecules to one of the O—P groups complete the crystal structure
