The Schiff base ligand 2-((2-(piperazine-1-yl)ethylimino)methyl)phenol (L-OH) and its complexes of Cu (II), Zinc (II) and Cadmium (II) were synthesized and characterized by FTIR, 1HNMR, UV-visible, elemental analysis, TGA and LC-MS. The structure of [C13H18CdCl2N3O] was confirmed by x-ray diffraction. The data obtained from the characterization shows that both complexes have composition of ML type. The thermal analysis results revealed high thermal stability for all the complexes and that the anions and the ligands are decomposed at first, and then followed by the decomposition of the whole complex at the subsequent steps. The resulting compounds were evaluated for antioxidant activity.Keywords: Antioxidant, Characterization, Synthesis, X-ray. |
