| Abstract | ||
| This paper describes the prepration of bis thiadiazole-2-thiol derivatives by conversion hydrazide derivatives of carboxylic acid to xanthate salt through its reaction with carbon disulfide. The bis thiadiazole derivatives were obtained through ring closur of xanthat salt by adding sulfuric acid as catalyst. Bis Thiadiazole-2-thiol derivatives have been used as ligands to prepare polymeric coordinated complexes by direct reaction between ligand and divalent ion(Co2+ , Ni2+ , Cu2+ , Zn2+ , Cd2+) in a basic aqueos solution. On the basis of IR , UV analytical studies and literature data the probable structures have been proposed , it has been found that the divalent metal ions coordinate with polydentate ligand BTH-H1-3 forming octahedral polymeric complexes. | ||
