摘要
测定了半乳糖醇铽配合物的晶体结构 .结果表明 ,糖的羟基和水分子同时与稀土离子配位 ,糖的羟基、水分子及氯离子之间形成广泛的氢键网络 .红外光谱结果表明 ,铕和铽对半乳糖醇具有相同的配位方式 .本文还测定了荧光光谱 。
The crystal structure of 2TbCl 3·C 6H 14 O 6·14H 2O was determined. The result shows that the hydroxyl groups of alditol and water molecules coordinate to Tb 3+ ion together while the hydroxyl groups of alditol, water molecules and chloride ions form an extensive hydrogen bond network. The FTIR results indicate that galactitol coordinates to Eu 3+ and Tb 3+ using the same coordination mode. The luminescence spectra of Eu and Tb galactitol complexes were also recorded and showed the characteristic emission spectra of the lanthanide ions.
