摘要: Dutt曾合成稀土离子与N,N-二(邻羟基亚甲基)乙二胺的稀土双希夫碱配合物。但未见报道Eu(Ⅲ),Tb(Ⅲ),Ho(Ⅲ),Tm(Ⅲ),Lu(Ⅲ)与双希夫碱N,N-二(邻羟基亚甲基)乙二胺的配合物。本工作合成了这5种双希夫碱配合物。 所用稀土氧化物纯度大于99.9%(上海跃龙化工厂)。水杨醛(CP,用前经减压蒸馏提纯)。稀土硝酸盐Ln(NO3)3·xH2O由稀土氧化物与硝酸反应制得。其余试剂均为分析纯。

Abstract: Five lanthanoid complexes of salicylidene ethylenediamine (L) have been synthesized and characterized by elemental analysis, IR. UV, DTA-TG, molar conductance, X-ray diffraction analysis. The compositions of the complexes were confirmed to be [Ln2L3(NO3)3](NO3)3·2H2O (Ln=Eu,Tb,Ho,Tm,Lu).
