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
