Studies on the Complexes of Rare Earths with the Unsaturated Acid (Ⅰ)——Preparation and Characterization of Complexes of Rare Earths with Propenoic Acid

本文用复分解法制得了十四种丙烯酸的稀土配合物,用化学分析法确定它们的组成为Ln(C_(3)H_(3)O_(2))_(3)·H_(2)O(Ln=La,Ce,Pr,Nd……Yb,Y);进而用红外光谱、紫外光谱、核磁共振谱等近代测试技术对这些化合物的性质和结构进行了研究。

In this paper, the metathetical reaction involving rare earth carbonates and propenoic acid has been successful in the preparation of Ln(C_(3)H_(3)O_(2))_(3)·H_(2)O(Ln = La, Ce,……Yb and Y). With the composition determined by chemicalanalysis, the experimental data obtained from a number of modern physical and spectroscopic studies of IR, UV, and ^(1)HNMR provided powerful evidence for the synthesis of new complexes. Their properties and structure have been discussed as well.
