title: Bis(1-{bis-[2-(diphenyl-phosphino-yl)eth-yl]phosphan-yl}-2-(diphenyl-phosphan-yl)ethane)dinitratoplatinum(II) methanol tetra-solvate.
abstract: 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. Hydrogen bonds from two methanol solvent mol-ecules to one of the O-P groups complete the crystal structure.
