Abstract
Polymeric carboxylatoruthenium complexes [Ru2(μ-RCO2)2(CO)4]n (1, R = H; 2, R = Me) react with (diphenylphosphino)ferrocene (FcPPh2) to give the corresponding discrete diruthenium complexes [Ru2(μ-RCO2)2(CO)4(FcPPh2)2] (3, R = H; 4, R = Me) in good yields. Compounds 3 and 4 were characterised by spectroscopic (NMR, IR and MS) and voltammetric methods. The crystal structure of 4 was determined by single-crystal X-ray diffraction.
