The Cr(III), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) complexes with a novel tetradentate ligand obtained by condensation of ethylenediamine with ortho-hydroxyphenylglyoxal have been synthesized and characterized by elemental analysis, molar conductance and magnetic susceptibility measurements, IR, UV-Visible and atomic absorption studies. The Cr(III), Fe(III) and Co(II) complexes possess six coordinate octahedral geometry whereas Ni(II), Cu(II) and Zn(II) complexes are square planar and tetrahedral respectively. Bactericidal and fungicidal activities of the compounds were evaluated in vitro by disc diffusion method. The perusal of antimicrobial activities of the compounds reveals that the complexes possess greater bactericidal and fungicidal activities against all the microbes in comparison to ligand which is due to their higher lipophilicity.
