The synthesis and coordination chemistry of a new dithiocarbamate prepared from dipyridylaminedithiocarbamate

Abstract

A new dithiocarbamate, dipyridylaminedithiocarbamate (DPADTC), was prepared and the coordination chemistry of this potentially ambidentate ligand was examined. The potassium salt of this new ligand reacts with a variety of MX 2 salts in methanol to yield M(DPADTC) 2 complexes. The copper, zinc and cadmium complexes have been isolated and characterized. The physical properties of this new ligand and compounds are discussed. The dithiocarbamate is a weakly coordinating S 2 ligand in the absence of oxygen donor solvents but reverts to a nitrogen donor ligand alone in the presence of such solvents. Insight into the nature of ambidentate coordination in such complexes is offered.
