Schiff base ligand obtained by the condensation of Glutaraldehyde with L-valine were complexed with Cu(II) , Ni(II) and Zn(II) transition metal ions. Structural features were obtained from their elemental analyses, magnetic susceptibility measurements, molar conductance data, IR, UV-Vis, 1H-NMR spectral studies and X-ray diffraction study. The UV-Vis and magnetic susceptibility studies suggest an octahedral geometry around the central metal ions. IR datas show that the ligand behave as tetradentate ligand coordinating through both carbonyl oxygen and terminal nitrogen atoms. The molar conductance measurements indicate that the complexes are non-electrolytic in nature. The powder XRD data shows that the complexes are microcrystalline. The antimicrobial activities of ligand and its complexes screened by Disc Diffusion method shows that the metal complexes were more potent than the parent Schiff base ligand against one or more bacterial and fungal species.
