Redox properties of the complexes of Co(II) and Pd(II) with the extended π system N,N′-ethylenebis(monothioacetylacetoniminate) ligand are studied in acetonitrile solvent at platinum and mercury electrode by cyclic voltammetry and controlled potential coulometry. The Co(II) complex undergoes a reduction process giving rise to the corresponding Co(I) species, stable in the electrolysis solution; the oxidation product, [Co{(sacac)2en}]+, stable in solid state, decomposes in solution phase.The electroreduction of the Pd(II) complex occurs by two subsequent cathodic processes, originating the unstable species [Pd{(sacac)2en}]− and [Pd{(sacac)2en}]2−. The anodic oxidation product is the species [Pd{(sacac)2en}]2+, from which the starting complex can be electrolytically regenerated.
