摘要

The complex [Cu(PANH)2(H2O)4·2H2O]n was synthesized through the coordination of 2-Carbonyl propionic acid-4-nitryl benzoyl hydrazine (PANH) and transition metal salt CuSO4·5H2O. The structure was determined and characterized by elemental analysis and X-ray diffraction. The single crystal was in the monoclinic system with the space group of P2/c. Super-oxygen activity of the Schiff base Cu complex was determined through NBT illumination reduction method and the mechanism was studies as well. The result indicated that the oxidation resistance of acylhydrazone complex could be enhanced by the synergistic effect fo Cu ions. And the magnetic study proved anti-ferromagnetism of the complex under low temperature.
