摘要： 在乙腈和丙酮中合成了冠醚B12C4与稀土硝酸盐的配合物RE(NO3)·B12C4·xH2O。通过金属离子的配位滴定、冠醚B12C4的分光光度测定、溶剂的气相色谱分析以及红外光谱、差热(DSC)与热重分析和X-射线衍射分析等方法研究了配合物的组成和性质。还在15±0.1℃测定了各配合物在乙腈中的溶解度。考察了重稀土(Tm、Yb和Lu)配合物1:1型向2:1型的转变。

Abstract: The complexes of the rare earth nitrates with benzo-12-crown-4 were synthesized in CH3CH or CH3COCH3All of the complexes RE(NO3)3·Bl2C4.xH2O (where RE=Pr, x=2; RE=Nd, x =0; RE=Y, Tm, Yb, Lu, x=3) were formed in the solid state. They were characterized by spectrophotometry, chemical analysis, infrared spectra, U. V. spectra, X-ray diffraction, chromatography of gases, thermogravimetric and differential thermal analyses. Besides, the solubilities of the complexes in CH3CN were determined at 15±0.1℃.
