用白氨酸分别和三种稀土硝酸盐在有机溶剂中首次合成了三种相应的1:2型固体配合物,经化学分析和元素分析确定了其组成为RE(Leu)_2(NO_3)_3·2H_2O(RE=Ce,Nd,Sm;Leu=DL-α-Leucine)。并通过X—粉晶衍射、红外光谱、TG—DTG和电导等对其性质进行了讨论。
Three kinds of solid complexes of 1: 2 were synthesized for the first time using leucine and three kinds of rare earth nitrate respectively. The chemical composition and elemental analysis of the three complexes were confirmed as RE (Leu) _2 (NO_3) _3 · 2H 2 O (RE = Ce, Nd, Sm; Leu = DL-α-Leucine). Their properties were discussed by X-ray powder diffraction, FTIR, TG-DTG and conductivity.
