SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL EVALUATION OF BINUCLEAR Fe(III), Co(II), Ni(II), Cu(II) AND Zn(II) COMPLEXES WITH SCHIFF BASE (E)-4-[(HYDROXYL PHENYLIMINO)METHYL]BENZENE-1, 2-DIOL
AbstractSchiff base ligand (E)-4-[(hydroxyl phenylimino)methyl]benzene-1, 2-diol (H3L) was prepared from the condensation reaction of Protochatechu aldehyde (3, 4-dihydroxybenzaldhyde) with 2-amino phenol. From the direct reaction of the ligand (H3L) with Co(II), Ni(II) and Cu(II) chlorides and Fe(III) and Zn(II) nitrates in 2M:1L molar ratio, the five new neutral complexes were prepared. The characterization of the newly formed compounds was done by 1HNMR, UV-Vis and IR spectroscopy and elemental analysis. The in-vitro antibacterial activity and antifungal activity of the metal complexes were studied and compared with that of free ligand. The Cupper complex shows the higher biological activity.
