测定了两个三元系统Ln(ClO~4)~3-PCBAAP-H~2O(Ln=La，Yb；PCBAAP：4-(对氯苯酰基)氨基安替比林，C~1~8H~1~6O~2N~3Cl)在30℃时的溶解度，发现两系统各有一个组成为Ln(PCBAAP)~4(ClO~4)~3·nH~2O(Ln=La，n=6；Ln=Yb，n=2)的不一致溶解化合物生成。参考系统的溶解度研究结果，合成了系列化合物Ln(PCBAAP)~4(ClO~4)~3·nH~2O(Ln=La，n=6；Ln=Pr，Nd，Sm，Gd，Yb，n=2)，通过化学分析及元素分析，IR光谱，TG-DTG，XRD和密度测定对其进行了表征。

The solubilities of the ternary systems Ln(ClO~4)~3-PCBAAP-H~2O (Ln=La, Yb) at 30℃ were determined, and the incongruent compounds, Ln(PCBAAP)~4(ClO~4)~3·nH~2O(Ln=La, n=6; Ln=Yb, n=2) were discovered in the systems. Based on the results of solubilities, the series compounds, Ln(PCBAAP)~4(ClO~4)~3·nH~2O(Ln=La, n=6; Ln=Pr, Nd, Sm, Gd, Yb, n=2) were synthesized by means of phase equilibrium method. The compounds were characterized by chemical analysis, elemental analysis, IR spectra, TG-DTG analysis, XRD and density determination, respectively.
