Mn（Ⅱ）, Co（Ⅱ）, Ni（Ⅱ） and Cu（Ⅱ） complexes of.5-mercapto-1,2,4-triazol-3-imine-2＇-hydroxynaphthaline have been synthesized and characterized by elemental analysis, IR, IH NMR, EI-mass, UV-Vis, and ESR （electron spin resonance） spectra, molar conductance, magnetic moment measurements, DC conductivity and thermogravimetric analysis. IR spectra conf.rm that the ligand molecule existed in both thione and thiole f.rms. The molar conduc- tance values indicate the complexes are nonelectrolyte. The magnetic moment values of.the complexes display paramagnetic behavior. All studies conf.rm the f.rmation of.an octahedral geometry f.r complex 1 and the other complexes have tetrahedral geometrical structures. The structures of.the complexes have also been theoretically studied by using the molecular mechanic calculations by the hyperchem. 8.03 molecular modeling program which conf.rm the proposed structures. The Schif.-base ligand and its metal complexes have also been screened f.r their antimicrobial activities.
