摘要： 稀土冠醚络合物的组成和稳定性不但与稀土离子直径和冠醚孔径是否匹配,而且也和阴离子及合成用的溶剂有关.因15-冠-5(简写15C5)的孔径(2.2Å)和大部分稀土离子直径相近.因此它们的络合物是研究孔径匹配关系的理想模型.

Abstract: Using dry acetone as solvent, the solid complexes of lanthanides, yttrium and scan-dium nitrate with 15-crown-5 have been prepared. According to elemental analysis, thecompositions of the complexes were found to be RE(NO3)3·15C5 for La-Eu and RE(NO3)3·15C5·3H2O for Gd-Lu, Y and Sc. Some of their. properties were determined bythermoanalysis, IR and XPS.

Key words: Rare earth complexes, Crown ether, Thermoanalysis, IR, XPS
