Crystal structure of {3-[3,5-bis­(2,6-di­methyl­phen­yl)-1,2-phenyl­ene]-1-(2,6,2′′,6′′-tetra­methyl-1,1′:3′,1′′-ter­phen­yl-5′-yl)imidazol-2-yl­idene}chlorido­(η⁶-p-cymene)ruthenium(II) benzene disolvate

The title compound, [Ru(C₄₇H₄₃N₂)Cl(C₁₀H₁₄)]·2C₆H₆, crystallized with two independent mol­ecules of benzene. One of the N-aryl moieties of the N-heterocyclic carbene (NHC) ligand underwent cyclo­metallation 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)°.
