A new series of complexes of Co(II), Ni(II), Cu(II) and Zn (II) with Schiff bases derived from the condensation of cinnamaldehyde with 4-amino-5-mercapto-s-triazole and 4-amino-5-mercapto-3-methyl-s-triazole have been synthesized. The complexes are characterized by elemental analyses,1H NMR, IR, electronic spectra and magnetic susceptibility measurements. The spectroscopic studies reveal that Schiff base acts as bidentate ligand with N, S donor set. Thermal studies of the complexes are also reported.
