Fund Project:

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.
