Abstract: The title compound, [Ru(C7F5O2)2(C10H14)(C21H24N2)]·2CH2Cl2, is formed as an orange crystalline powder by the reaction of RuCl2(p-cymene)(IMes) and AgOCOC6F5 in anhydrous tetrahydrofuran (IMes = 1,3-dimesityl-2,3-dihydro-1H-imidazol-2-ylidene). The asymetric unit consists of two independent [Ru(C6F5COO)2([eta]6-p-cymene)(IMes)] complexes and four dichloromethane solvent molecules. In each complex molecule, the Ru atom presents a pseudo-octahedral environment with the p-cymene ligand occupying three facial coordination sites, while the remaining coordination positions are occupied by the O atoms of the pentafluorobenzoate ligands and by the imidazolylidene ligand.
