Synthesis, crystal structure and catalytic activity in reductive amination of di-chlorido-(η--cymene)(2'-di-cyclo-hexyl-phosphanyl-2,6-di-meth-oxy-biphen-yl-κ)ruthenium(II).

The title compound, [RuCl(CH)(CHOP)] (), crystallizes in the monoclinic space group 2/ with two crystallographically independent mol-ecules ( and ) in the asymmetric unit. The geometries of both mol-ecules are very similar and distinguished only by the twist angles of the two benzene rings in the phosphine substituents [89.54 (14) and 78.
