Popis: Cyclic voltammetry and galvanostatic coulometry techniques were used to determine how the redox properties of osmium binuclear μ-oxocarboxylates [Os2 IV(μ-O)(μ-O2CR)2Cl4L2] (R = CH3, CCl3; L = PPh3 and R = CH3; L = AsPh3) are influenced by the nature of the bridging carboxylate ligand RCOO– and ligand L. It was shown that all compounds in solution of dichloromethane undergo two single-electron reduction processes. The data obtained were compared with the DFT calculations of the electronic structure of the model complexes [Os2 IV(μ-O)(μ-O2CR)2Cl4L′2] (R = CH3, CCl3; L′ = PH3 and R = CH3; L′ = AsH3).
