trans-Chloro(methyl)bis(tricyclohexylphosphine)platinum(II)

The crystal structure of the title compound, [PtCl(CH3)(C18H33P)2], is isostructural with various platinum(II) and palladium(II) complexes containing two bulky tricyclohexylphosphine ligands in a trans orientation. The Pt atom resides on an inversion centre, resulting in a 50% statistical disorder in the chloro and methyl positions. The most significant geometrical parameters are Pt-P 2.3431 (8), Pt-Cl 2.440 (4) and Pt-C1 2.179 (13) A, and P-Pt-P 180, P-Pt-Cl 89.15 (12) and 90.85 (12), and C-Pt-Cl 172.7 (5) degrees. The effective and Tolman cone angles for the tricyclohexylphosphine ligands were calculated as 160 and 162 degrees, respectively.
