含茂基及丁二酰亚胺基混合配体镧系金属有机化合物的合成及表征

Synthesis and characterization of mixed ligand lanthanide organometallics involving both cyclopentadienyl and succinimido ligands

在室温下由丁二酰亚胺与 Cp3L n在 THF 溶液中反应 ,得到较高产率的 Cp2 L n(suc) ,Ln=Yb、Er、Dy、Sm。这些化合物经元素分析、红外光谱和质谱鉴定 。

Four complexes of the general formulea,Cp 2Ln(suc),(Cp=Cyclo pentadienyl;Ln=Yb、Er、Dy、Sm;suc=succinimido);have been synthesized by reacton of Cp 3Ln with succinimide in THF.All the complexes were characterized by elemental analysis,IR and MS,showing that are dimers with succinimido as bridging groups.
