Electrochemistry and redox behaviour of transition metal dithiocarbamates

Publisher Summary Recently, an article was published on 1,2-dithio ligands, and have stressed the versatility of these ligands and the academic and industrial importance of their metal complexes. Complexes of molybdenum and tungsten with bidentate sulfur ligands have been investigated extensively. In recent years, the work in this field has been escalated by the impetus of designing models of such bioinorganic enzymes as nitrogenase and xanthine oxidase. Oxidation of copper dithiocarbamate complexes of Cu(1) with chlorine or bromine yields paramagnetic compounds with the composition CuX 3 (R 2 dtc), in which the copper has a formal oxidation-state of (IV), but the structure of these compounds is obscure. The complexes of the 1,1-dithio ligands with the Group I transition metals have been studied in considerable detail and have been extensively reviewed by Coucouvanis.

Morpholine-4-carbodithioate (mdtc) complexes of titanium(IV), vanadium(IV), chromium(III), manganese(III), iron(III), cobalt(III), nickel(II), copper(II), zinc(II), and cadmium(II) have been prepared and characterised by analysis and magnetic and spectroscopic techniques. The complexes are of the type M(mdtc)n, where n is the oxidation state of the metal ion except for vanadium(IV), where the complexing species is the VO2+ ion. Some adducts with the parent base morpholine are also reported.
