✦ Synopsis

Cis-and trans-dichlorobis(tertiary phosphine)platinum(II) complexes [PtClz(PMeXPh,.J)z] (x = 0,1,2,3) and [PtCl,(PEt,),] have been investigated by cyclic voltammetry and controlled potential electrolysis in acetonitrile solution by using both platinum and mercury electrodes. The results show that the investigated platinum(H) compounds can be either oxidized or reduced to phosphine complexes of platinum(IV) and platinum(O), respectively. The dependence of the oxidation and reduction potential values on the nature of the phosphine ligands is discussed. Furthermore, it has been found that the trans-complexes are more easily oxidized than the cis-analogues and that a slow cis-trans isomerisation occurs in acetonitrile solution.
