New five metal complexes of Cu(II), Cd(II), Sn(II), Zn(II) and Ni(II) with Schiff base ligand 4-(Benzylidene-amino)- 5-pyridin-4-yl-4H-[1,2,4]triazole-3-thiol were synthesized in ethanol as a solvent. The new compounds were characterized by different physicochemical techniques such as melting point, flame atomic absorption, elemental analysis C.H.N.S, FT-IR, UV-visible spectrophotometry, 1H NMR, conductivity and magnetic susceptibility measurements. The Schiff base ligand acted as bidentate and coordinated to the metal atoms via the azomethine-N and S atom of thiol group. From the spectral studies, square planar geometry was proposed for the copper complex. The other complexes were proposed to be tetrahedral.
