Preparation , characterization and molecular models of a ligand derivative of the 1,3,4-thiadiazole and some transition metal complexes

Abstract

That thiadiazoles derivative are biologically active as antimicrobial agent(1) . therefore, the derivative of the 1,3,4-thiadiazole has prepared along with series of their metal complexes. The reaction of ligand; 2-amino-5-{[(diethylamino)carbonothioyl]dithio}1,3,4-thiadiazole with Cu(II) , Fe (II) , Ni (II) ions yield the following complexes [Cu(ligand)2Cl2], [Fe(ligand)2(H2O)2]SO4, . [Ni(ligand)2Cl2] . The ligand and their metal complexes were characterized using the appropriate techniques, which included melting point, IR,and UV-visible .According to the data obtained, the structural formula with three dimensions of our complexes were suggested.
