The work includes synthesis and characterization of new ligand and its complexes with divalent metal ions such as cobalt, nickel, copper and zinc. This project includes firstly, the synthesis of Schiff base by reacting P-aminoacetophenone with 2-amino-6-methylpyridine by the reflux reaction for 6 hr. and at 70 ° C. The second step involves the synthesis azo-Schiff base containing ligand which was prepared by the reaction of the Schiff base with the heterocyclic 1,2,4-triazole. The prepared ligand was characterized using spectroscopic methods such as Infrared spectrum, UV-visible spectrum, 1HNMR and 13CNMR spectrum. In the third step, the ligand complexes were prepared by the reaction between the ligand and the metal ion salts to obtain the related metal complex. Some properties of the prepared compounds were studied such as the solubility. The prepared complexes were characterized using IR spectroscopy, UV-Visible, conductivity, magnetic sensitivity, and the atomic absorption technique was used to determine the percentage of each metal in its complex.
