Abstract

The title compound, [Ru(C$7$F$5$O$2$)$2$(C$10$H$14$)(C$21$H$24$N$2$)]$\cdot$2CH$2$Cl$2$, is formed as an orange crystalline powder by the reaction of RuCl$2$(p-cymene)(IMes) and AgOCOC$6$F$5$ 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(C$6$F$5$COO)$2$($\eta$$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.
