Abstract

The electrochemical and spectroelectrochemical behaviour of the [Ru 3O(O 2CCH 3) 6 (py) 2(dmso)] + complex (py = pyridine, dmso = dimethylsulphoxide) is discussed. Four reversible waves were observed around 2.1, 1.2, 0.2 and −0.95 V, corresponding to the successive redox couples Ru IVRu IVRu III/…/Ru IIIRu IIRu II, respectively. Dramatic spectral changes and splitting of the electrochemical waves around 0.2 V, were ascribed to an intramolecular O-bound to S-bound dmso linkage isomerization reaction. In pure acetonitrile solutions, a parallel dissociation of O-bound dmso is also observed. The evaluation of the kinetic and equilibrium constants for the dissociation and linkage isomerization reactions is reported.
