Sulphur-nitrogen donor chelating agents, i.e. dithiocarbazates and their metal complexes have been widely studied because of their unusual physico- chemical properties, novel structural features, potentially useful chemotherapeutic properties and their relevance to biological systems. Dithiocarbazates and their metal complexes have experienced long standing applications in the catalysis of chemical and petrochemical processes, as analytical reagents and substitutes for dithiocarbamates as agricultural fungicides and accelerators of vulcanization of rubber. The dithiocarbazates...
