摘要: 研究桥联多核配合物的磁性不仅有助于了解桥联多核配合物在生物体内所起的各种生物功能,而且可为分子铁磁体的设计和合成提供信息.某些过渡金属配合物已显示了体外抗艾滋病和抗癌活性,有关桥联多核配合物在这方面的研究甚少.

Abstract: Two new novel binuclear cobalt (Ⅱ) complexes, namely,[Co2 (4PT) (Phen)4]( ClO4 )2· 3H2O (complex 1) and[Co2 (4PT)(NPhen)4] (ClO4)2·2H2O (complex 2) (4PT=4-nitrophthalato, Phen=l,10-phenanthroline, NPhen = 5-nitro-1,10-phenanthroline) have been synthesized. The complexes were characterized by elemental analysis, IR, UV-Vis spectra and electronic conductance. The variable-temperature magnetic susceptibility of the complexes was measured over 77~300 K. The data were analyzed by using the magnetic susceptibility equation based on Heisenberg spin-exchange operator, and the exchange integrals for complex 1 and complex 2 were found 2J= - 8.6 cm-1 and 2J=-4.3 cm-1,respectively. Experiments of inhibiting human leukemia cell, stomach cancer cell and carcinoma of nasopharyngeal cancer cell in vitro were made,and found that the complexes exhibited a relatively strong function of inhibiting these three kinds of cancer cells.

Key words: nitrophthalate, binuclear Co(Ⅱ) complex, magnetism, bioactivity
