Electrochemical and Chemical Properties of Dithiocarbamato Complexes of Ruthenium(II), Ruthenium(III), and Ruthenium(1V) S. H . W H E E L E R , B. M. MATTSON, G. L. MIESSLER, and L. H . PIGNOLET* Received June 22, 1977 An electrochemical study of several N,N-diethyldithiocarbamato (Etldtc) complexes of Ru(II), Ru(III), and Ru(IV) was carried out. [ ( C O ) R ~ ( d t c ) ~Rl ~ ,( d t c ) and ~ , CIRu(dtc), were studied by dc, ac, and cyclic voltammetric techniques in the solvents acetonitrile, propylene carbonate, and methylene chloride. The results indicate that the bimetallic complexes a- and P - [ R ~ ~ ( d t c ) are ~ ] +not formed as primary electrochemical oxidation products of Ru(dtc), or reduction products of C l R ~ ( d t c ) ~The . electrochemical oxidation product of R ~ ( d t c in ) ~CH3CN is [ (CH3CN)Ru(dtc)3]', and the metal-containing reduction product of C l R ~ ( d t c )which ~, exists as [(CH3CN)Ru(dtc)3]+Cl-in CH3CN, is R ~ ( d t c ) ~In. propylene carbonate, CIRu(dtc)3 is undissociated and exhibits a one-electron oxidation ( E l l 2 = 0.97 V) and a two-electron reduction ( E l l 2= -0.77 V) to Ru(dtc)
