                                摘要:
                                A new Schiff base ligand as salt (KL) was synthesized using potassium salt of DL-beta-phenylalanine and 2-hydroxy-1-naphthaldehyde. Two binuclear complexes of this ligand, [M2L2(CH3COO)(2)] (M = Cu(II), Ni(II)) have been synthesized and characterized by elemental analyses, IR, UV spectra, and molar conductance. Their prohibitive action on the superoxide anion free radical (O-2(-center dot)) was estimated by the NBT illumination deoxidizing method (Methionine-lactoflavin illumination method). The results suggested that the ligand and its complexes had the prohibitive action on O-2(-center dot).
