(η6-Benzene)dichlorido(chlorodicyclohexylphosphane-κP)ruthenium(II)chloroform monosolvate

The title compound, [RuCl2(eta(6)-C6H6)(C12H22ClP)]center dot CHCl3, was prepared by reaction of [RuCl2(eta(6) -C6H6)](2) with chlorodicyclohexylphosphane in CHCl3 at 323 K under argon. The Ru II atom is surrounded by one arene ligand, two Cl atoms and a phosphane ligand in a piano-stool geometry. The phosphane ligand is linked by the P atom, with an Ru-P bond length of 2.3247 (4) angstrom. Both cyclohexyl rings at the P atom adopt a chair conformation. In the crystal, the Ru II complex molecule and the chloroform solvent molecule are linked by a bifurcated C-H center dot center dot center dot Cl, Cl) hydrogen bond. Intramolecular C-H center dot center dot center dot Cl hydrogen bonds are also observed.
