Özet

New imine-oxime ligands H3L1-H3L3 have been obtained from reactions of the Schiff base ligands H2B1-H2B3 with monochloroglyoxime. Mononuclear copper(II), cobalt(II), nickel(II), vanadyl(IV) and zinc(II) complexes of the imine-oxime ligands H3L1-H3L3 have been prepared and characterized by elemental analyses, infrared and electronic spectra, magnetic moment and molar conductance data. The molar conductance data show that the complexes are non-electrolytes. When the imine-oxime ligands react with the metal salts in a 2:1 ratio, they behave as dibasic bidentate ligands towards one metal ion. The nickel(II) and zinc(II) complexes are diamagnetic. The H-1(C-13)-nmr spectra of all ligands and nickel(II) and zinc(II) complexes of the ligands H3L1-H3L3 have been recorded. Mass spectra of the imine-oxime ligands and their nickel(II) and zinc(II) complexes were recorded. Some of the ligands and metal complexes have antibacterial activity.
