摘要： 合成了稀土N,N'-亚乙基双(水杨醛缩亚胺)(H2salen)双核配合物，通过元素分析、热分析、紫外、红外、远红外光谱、磁化率及1H、13C NMR谱与T1的测定，确定了他们与前人合成的配合物有所不同，其化学组成为[Ln2(H2salen)3(NO3)4](NO3)2·3H2O(Ln=La,Pr,Nd,Sm,Gd,Tb,Er,Yb及Y),并对它们的配位作用、波谱及可能应用进行了探讨。

Abstract: A synthetic method of LnH2salen complexes was described and a series of binuclear complexes were obtained. The complexes were characterized by elemental analysis, TG DTA, UV IR spectroscopy, magnetic susceptibility,1H,13C NMR measurements and the 13C-spin-lattic relaxation time was investigated for elucidation of their complexation. The composition of the complexes obtained were confirmed as [Ln2(H2salen)3(NO3)4)3(NO3)4](NO3)2?3H2O, where Ln=La, Pr, Nd, Sm, Gd, Tb, Er, Yb, and Y. A possible structure was suggested and the catalytic activity of the complexes for MMA polymerization was discussed.

Key words: H2salen, lanthanide complex, binuclear complex, synthesis, spectral behavior
