The crystal structure of the title compound, [PtCl-(CH3)(C18H33P)(2)], is i
sostructural with various platinum(II) and palladium(II) complexes containi
ng two bulky tricyclohexylphosphine ligands in a trans orientation. The Pt
atom resides on an inversion centre, resulting in a 50% statistical disorde
r in the chloro and methyl positions. The most significant geometrical para
meters are Pt-P 2.3431 (8), Pt-Cl 2.440 (4) and Pt-Cl 2.179 (13) Angstrom a
nd P-Pt-P 180, P-Pt-Cl 89.15 (12) and 90.85 (12), and C-Pt-Cl 172.7 (5)degr
ees. The effective and Tolman cone angles for the tricyclohexylphosphine li
gands were calculated as 160 and 162 degrees, respectively.
