香草醛缩组氨酸稀土镧、钕、钐、铈配合物的合成及表征

Synthesis and Properties of Four Rare Earth Complexes with Vanillylidene-histrdine Schiff Base

合成了组氨酸缩香草酸席夫碱(以L表示)稀土元素La、Nd、Sm、Ce4种配合物,通过元素分析、摩尔电导、差热 热重分析,红外光谱、紫外光谱等手段,确定配合物的组成为KREL(H2O)(NO3)·2H2O并对其结构和物理化学性质进行了研究。

Four schiff base complexes KREL(H2O)(NO3)·2H2O(where RE=La(Ⅲ), Nd(Ⅲ), Sm(Ⅲ), Ce(Ⅲ), L=Vanillylidene=histrdine schiff base) were synthesized and characterized by elemental analysis, molar conductance, DADTA thermal analysis, electronic spectrum and infrared spectrum measurements. The possible structure of the complexes was discussed.
