Abstract

Two new mixed ligand ruthenium(I) complexes of the composition [Ru ₂(O₂CR)₂(CO)₅] (where R = (2,4-CF₃)₂C₆H₃ (1) and (3,5-CF ₃)₂C₆H₃ (2)) have been prepared by melt reactions, and both have been fully characterized. Crystals of 1 and 2 have been obtained by gas phase sublimation of crude products at 124 and 150°C, respectively. The X-ray diffraction studies have revealed a tetranuclear 'dimer of dimers' core structure in both cases. In 1 two diruthenium(I) units cis-bridged by two carboxylates each are coordinated through the Ru⋯O axial interactions at 2.301(2) Å. In contrast, complex 2 shows the direct Ru⋯Ru bonding of two diruthenium units at 2.9065(9) Å. The Ru-Ru distances within the dinuclear units are 2.6654(7) and 2.6859(8) Å in 1 and 2, respectively.
