The first (trifluoromethyl)tetramethylruthenocene-based ruthenium pincer complex RuCl(CO)[{2,5-(Bu2tPCH2)2C5H2}Ru(C5Me4CF3)] was synthesized by cyclometallation of the bisphosphine ligand {1,3-(Bu2tPCH2)2C5H2}Ru(C5Me4CF3) with RuCl2(DMSO)4 in 2-methoxyethanol in the presence of NEt3. The new complex was fully characterized by 1H, 19F, 31P{1H}, 13C{1H} NMR and IR spectroscopy.
