| Abstract: Two new heteropolynuclear metal complexes ［Ni(phen)2］3［Cr(ox)3］2·8H2O(1) and ［Ni(bipy)2］2［Cr(ox)3］NO3·4H2O(2)(phen=1,10-phenanthroline, ox=oxalato, bipy=2,2-bipyridine) have been synthesized and characterized by elemental analyses, IR, TG-DTA and diffuse reflectance UV-VIS spectra. The temperature dependence of the magnetic susceptibilities of the complexes have been studied over the range 73.6～300K. The results show that ferromagnetic spin exchange interaction exist between Cr(Ⅲ) and Ni(Ⅱ) in the complex (1). The magnetic property of the complex(2) abides Curie law. |
