A series of metal complexes of Co(II), Ni(II), Cu(II) and Zr(IV) with a Schiff base derived from salicyaldehyde and salicyloyl hydrazide were synthesized and characterized by several techniques, including elemental analyses, molar conductance, magnetic moments, electronic, 1H NMR, mass, IR, ESR spectra, and thermal studies (TGA & DTA). All the complexes are coloured solids, air stable, non-hygroscopic and soluble in DMF and DMSO only and are non-electrolytes. The magnetic moment values and electronic spectral data indicate a square planar geometry for Co(II), Ni(II) and Cu(II) and octahedral geometry for Zr(IV) complexes. IR spectral data suggest that the ligand behaves as dibasic tridentate with ONO (enol form) donor sequence towards Co(II), Ni(II), Cu(II) and Zr(IV) complexes. The thermal data has been investigated to observed degradation pattern and kinetic parameters Entropy Change (∆S), Free Energy Change (∆F) and apparent entropy change (S*) were calculated using Freemann-Carroll and Sharp-Wentwoth method. ESR spectra of copper complex are recorded and discussed. The antimicrobial activity of the ligand and its metal complexes by well diffusion method against Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli and Klebsiella pneumoniae are also reported. The complex exhibit increased activity than the ligand.
