Tricarbonylbis(tricyclohexylphosphine-κP)ruthenium(0) toluene solvate

Abstract

The title compound, [Ru(C18H33P)2(CO)3]·C7H8, shows a distorted trigonal-bipyramdial coordination around the central Ru atom, with the two phosphine ligands occupying the axial positions. Two toluene mol­ecules per asymmetric unit with site-occupation factors of 0.5 are observed. One of them forces two of the CO ligands to enclose a wider C—Ru—C bond angle [127.5 (3)°] than in the solvent-free crystal structure of [Ru(PCy3)2(CO)3] (Cy is cyclo­hexyl).
