(η(6)-Benzene)-dichlorido-(chloro-dicyclo-hexyl-phosphane-κP)ruthenium(II) chloro-form monosolvate.

The title compound, [RuCl2(η(6)-C6H6)(C12H22ClP)]·CHCl3, was prepared by reaction of [RuCl2(η(6)-C6H6)]2 with chloro-dicyclo-hexyl-phosphane 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) Å. Both cyclo-hexyl rings at the P atom adopt a chair conformation. In the crystal, the Ru(II) complex mol-ecule and the chloro-form solvent mol-ecule are linked by a bifurcated C-H⋯(Cl,Cl) hydrogen bond. Intra-molecular C-H⋯Cl hydrogen bonds are also observed.
