摘要
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。
This paper introduces three 1:2 solid complexes of DL a Leucine with rare earth nitrates prepared from organic mixed solvent for the time. the composition of the complexes have been determined by chemical analysis, elemental analysis. The general formula of these complexes is RE (Leu)_2 (NO_3)_3·2H_2O (RE=Ce, Nd, Sm; Leu=DL-α-Leucine). The complexes characterized by X—ray powder diffraction, IR, TG—DTG and electric conductivity in agueous.
