The metal complexes of Co2+ and Ni2+ 1,2,3-triazole mixed ligand have been synthesized. The synthesized complexes in different ratios have been characterized by element chemical analysis, molar conductance and Uv-visible and FTIR spectroscopic studies.IR spectra data suggests the involvement of sulphur and nitrogen in coordination to the central metal ions. On the basis of spectral studies and elemental analysis, a tetrahedral geometry was assigned for the nickel complexes while dimerization was suspected for cobalt(II) complexes.The free ligand and metal complexes were tested in vitro against a number of microorganisms (fungi and bacteria) in order to assess their microbial properties. They are found to be proactive against fungi and bacteria upon the metal complexes, nickel complexes performed better than the cobalt complexes.
