The present work is concerned with synthesis and study on metal complexes of Co(II), Ni(II) amd Cu(II) with bidentate Schiff base ligand, 2-methyl -[3(hydroxyl butyl)]- 3, 1(4H) quinazoline -4- Hydrazone (MHBQH). The complexes have the general formulae [(ML)2 X2], Where M=Co(II), Ni(II) and Cu(II); L=MHBQH and X=NH3, pyridine, α, β and γ picolines. The structure of the ligand, mode of bonding and overall geometry of the complexes were determined through, Infrared, electronic spectral studies of elemental analyses, molar mass, magnetic susceptibility and molar conductance. These studies revealed octahedral complexes for Co(II) and Ni(II) and distorted octahedral geometry for Cu(II) complexes. Biocidal activity of the ligands and its metal complexes against several organisms, Escherichia coli and Staphylococcus aureus are reported. Compounds exhibited the high effect of activity.
