... um dichloride in 1 : 2 molar ratio, mixed ligand complex in 1 : 1 : 1 molar ratio by the reaction of dithiocarbonate, alkylene dithiophosphate and metal salt in aqueous medium and their adducts with phosphorous and nitrogen donor ligand in 1 : 1 and 1 : 2 molar ratio. These complexes have been characterized by elemental analyses, mass, IR and heteronuclear NMR (1H, 31P and 13C) spectroscopic analysis. Thermal and redox properties of complexes were studied by thermogravimetric analysis and cyclic voltammetry. These studies confirm that in the nitrogen and phosphorous donor complexes the geometry around the cadmium metal centre is distorted octahedral, and in the parent cadmium dithiocarbonate complex it is distorted tetrahedral. The dithiocarbonate ligands and some selected complexes were screened against Fusarium oxysporum shows that the free ligands reveal significantly less activity compared to the corresponding cadmium complexes.
