A Schiff base has been prepared by the condensation of 4- amino -3,5-dimercapto,1,2,4-triazole with 2,4-diaminobenzaldehyde. The ligand has been used for complexation with Mn(II), Cu(II) and Zn(II) metal ions. The complexes have been characterized by their elemental analysis, molar conductivity, magnetic susceptibility, IR spectra and electronic spectra. The very low value of molar conductivity of complexes shows their non-electrolytic nature. The comparison of IR spectra of complexes with that of free ligand reveals that the ligand is coordinated through azomethine nitrogen and deprotonated thiolsulphur forming five membered heterochelates. The magnetic moment values and electronic spectral bands clearly indicate that octahedral geometry around metal ions in complexes.
