Synthesis and Characterization of Some Schiff BaseComplexes Containing Heterocyclic Compounds With Cobalt(II) , Nickel(II), Copper(II) and Zinc(II)

The synthesis of complexes for cobalt(ii) , nickel(ii), copper(ii) and zinc(ii) with new ligandsschiff base ; n-[5-(phenyl)2-(amino)1,3,4-thiadiazolebenzylidene] (l1) and n-[5-(phenyl)2-(amino)1,3,4- thiadiazole-4-n-dimethylbenzylidene] (l2) have been prepared and characterized by, atomic absorption spectrophotometer (aas),infrared spectra , electronic spectra, molar conductivity measurements and magnetic moment measurements ; it has been found that the ligands behaves as a neutral bidentate , ligands forming chalets with 1:2 (metal : ligand), octahedral structure is suggested for metal complexes according to the analytical results.
