Abstract |
A new Schiff base (HL2) ligand(4-{2-[(2-Hydroxy-benzylidene)-amino]-ethyl}-benzene-1, 2-diol) has been synthesized by condensing of 4-(2-Amino-ethyl)-benzene-1,2-diol and 2-Hydroxy-benzaldehyde. In turn, its transition metal complexes were prepared having the general formula; [Ni(L2)2], [Pd(L2)2] and [Pt(L2)22Cl]. The prepared ligand and its metal complexes Ni(II), Pd(II) and Pt(IV) have been characterized by FT-IR spectra, 1H-NMR elemental analysis, metal content, chloride containing, molar conductance, UV-Vis spectra, magnetic susceptibility, MS spectra and thermal analysis TGA. The consequences proposed that Schiff base acts like a bidentate ligand for all the prepared complexes. The antioxidant performance of as-prepared compounds were inspected using the DPPH radical scavenging method the compounds showed antioxidant activities of scavenging free radicals. Keywords: Antioxidant Activity, Dopamine, TGA, Charge transfer. |
