The strong electron donating properties of the 1,3-dimethylbenzimidazol-2-ylidene, made the eta6-p-cymene more labile from the Ru centre with an adduct initially formed at His15. To fill the coordination sphere of the Ru, Arg14 and water became coordinated to the Ru centre. The loss of the cymene ligand destabilized the Ru(II) oxidation state resulting in an oxidation to Ru(III). Ultimately forming a dichlorido(1,3-dimethylbenzimidazol-2-ylidene)ruthenium(III) ligand
