Synthesis, characterization, anti-bacterial activity study of vanillin schiff base complexes

الملخص EN

The 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.
