AbstractThe Fe(II), Co(II), Ni(II) Cu(II), Zn(II) and Hg(II) complexes were prepared by reacting their salts with the derived Schiff base ligands from condensing vanillin and o-phenylenediamine with a ratio (1:1), (2:1) respectively. Ligands and their complexes were distinguished using analytical, physical and spectroscopic methods. The elemental analysis values show that stoichiometry to be 1:1 [M:L]. Molar conductivity measurements detect that the complexes are non-electrolytic .From the information obtained through electronic measurements, magnetic sensitivity .The square planar geometry around of Ni(II) and Cu(II), and tetrahedral geometry around of the other metals . The prepared complexes showed different activity towards inhibiting bacterial growth for E. coli k.pneomonia
