Electrochemical studies of the fraras-dichloro-bis (diphenylphosphino) methane rhenium in tetrabutylammonium perchlorate/dichloromethane have been performed using cyclic and convolution potential sweep voltammetry. At room temperature, it was found that the complex isomerises on oxidation from the irons- to the cis-isomer and returns back to the original complex form on reduction at lower potentials. The electrode mechanisms were proposed and discussed on the basis of the "square-scheme". Upon cooling to 233 K, the cyclic voltammetric behaviour shows a single reversible couple in the region expected for the oxidation of trans-[ReC\2 (dppm)2]. Furthermore, the homogeneous and heterogeneous rate constants of the isomerisation reaction were evaluated.
