Crystal structure of {3-[3,5-bis-(2,6-di-methyl-phen-yl)-1,2-phenyl-ene]-1-(2,6,2'',6''-tetra-methyl-1,1':3',1''-ter-phen-yl-5'-yl)imidazol-2-yl-idene}chlorido-(η(6)-p-cymene)ruthenium(II) benzene disolvate.

Abstract

The title compound, [Ru(C47H43N2)Cl(C10H14)]·2C6H6, crystallized with two independent mol-ecules of benzene. One of the N-aryl moieties of the N-heterocyclic carbene (NHC) ligand underwent cyclo-metallation to form a five-membered ruthenacycle. The complex has a three-legged piano-stool structure with two C atoms incorporated in the five-membered ruthenacycle and a Cl atom as legs. The ruthenacycle is essentially coplanar with the imidazole ring of the NHC ligand, making a dihedral angle of 0.85 (8)°.
