title: (η(6)-p-Cymene)(1,3-dimesityl-2,3-dihydro-1H-imidazol-2-yl-idene)bis-(pentafluorobenzoato-κO)ruthenium(II) dichloro-methane disolvate.
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 tetra-hydro-furan (IMes = 1,3-dimesityl-2,3-di-hydro-1H-imidazol-2-yl-idene). The asymetric unit consists of two independent [Ru(C6F5COO)2(η(6)-p-cymene)(IMes)] com-plexes and four dichloro-methane solvent mol-ecules. In each complex molecule, the Ru atom presents a pseudo-octa-hedral environment with the p-cymene ligand occupying three facial coordination sites, while the remaining coordination positions are occupied by the O atoms of the penta-fluoro-benzoate ligands and by the imidazolyl-idene ligand.
