PREPARATION AND ELECTROCHEMICAL BEHAVIOR OF TRIS DITHIOCARBAMATO COMPLEXES [BU4N]M(ET2DTC)3 WITH M=BA, ZN, CD, AND HG

The compounds [Bu4N]M(R2dtc)3 (M = Ba, Zn, Cd and Hg; R = Me, Et) have been prepared. Conductivity measurements and an electrochemical oxidation study with pulse polarographic and cyclic voltammetric techniques show that in acetone solutions the barium tris anion, Ba(Et2dtc)- 3, is completely dissociated into the bis complex, Ba(Et2dtc)2 and a ligand ion, Et2dtc-; the zinc and mercury tris anions are not completely dissociated and the cadmium anion only to a minor extent. © 1979.
