The reduction at the mercury electrode of a series of ruthenium(III) dithiocarbamates in dimethylsulphoxide (DMSO) has been investigated using D.C. A.C. polarography, chronoamperometry, coulometry (controlled potential electrolysis) and cyclic voltammetry. Tris(N,N-disubstituted dithiocarbamato) complexes of ruthenium exhibit two one-electron polarographic waves in the potential range 0.00 to 2.20 volt relative to Ag/AgClO4 (DMSO) reference electrode. The first reduction, at approximately — 0.950 volt, is quasi-reversible. The [Ru(II) (dAdtc)3]− complexes resulting from this reduction are susceptible to dissociation, releasing the free dialkyldithiocarbamate anion.
