Abstract
The cathodic and anodic behaviour of the complexes [ReCl3(PMe2Ph)3] and [ReCl4(PMe2Ph)2] has been studied at platinum and mercury electrodes in acetonitrile solvent. The reduction and oxidation products have been identified and both thermodynamic and kinetic aspects of the involved electrode mechanisms have been studied. In particular, new rhenium derivatives such as [ReCl3(PMe2Ph)3]+. [ReCl4(PMe2Ph)2]− and [ReCl3(PMe2Ph)2(MeCN)]+, have been prepared. In addition the species [ReCl4(PMe2Ph)2] has been obtained in a yield higher than that obtained by conventional chemical methods. The EView the MathML source values of several redox couples of rhenium complexes have been calculated and compared with the corresponding values of the technetium ones; the stability of analogous rhenium and technetium compounds has been also discussed.
