This Schiff base ligand was synthesized via condensing [2-pyridine carboxaldehyde] with [2-amino-5-phenyl-1,3,4-thiadiazol] in an alcoholic solution. For preparing complexes, two tetradentate Schiff bases ligand were employed with two metal ions of Co2+, Ni2+, Cu2+ and Zn2+ as dinuclear formula M2L2. The synthesized ligand and its metal complexes were well characterized using FTIR, UV-Vis absorption, elemental analysis, thermal analysis, 1H-NMR, and mass spectroscopy. Based on these characterizations, the chemical structures of the ligand and the metal complexes were confirmed. Furthermore, the electronic and magnetic properties of the prepared metal complexes were clearly understood.
