Abstract

ABSTRACT

The synthesis and characterization of Schiff base and the complexities of metal ions and the evaluation of its antioxidant activities against 1.1-Diphenyl-2-picrylhydrazyl (DPPH) will compared with standard natural antioxidants and ascorbic acid. These prepared materials gave results are due exhibit excellent radical scavenging activities for all complexes with new prepared from reaction Schiff base and metal ions for [ Mn(II), Zn (II), Cd(II), Pd(II) and Hg(II) ]. The complexes prepared characterization by spectral methods (ultraviolet visible, infrared and mass spectra) will be identified in addition to the element micro analysis, (F.A.A.), magnetic sensitivity. The molar conductance values indicated that the complexes derived from Mn(II), Zn(II), Cd(II), Hg(II) chloride and Pd(II) bromide have nonelectrolytic nature. IR spectra indicated that the ligand acts as neutral bidentate moiety in all complexes. According to the results of diagnosis and analysis gave the all complexes form tetrahedral except in Pd (II) complex square planar. The antioxidant activities of the metal complexes will be examined using the DPPH radical scavenging method the compounds exhibited antioxidant properties of scavenging free radicals.
