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,得到稀土离子的特征光谱.

关键词: 半乳糖醇, 荧光光谱, 稀土配合物

Abstract: The crystal structure of 2TbCl3·C6H14O6·14H2Owas determined. The result shows that the hydroxyl groups of alditol and water molecules coordinate to Tb3+ ion together while the hydroxyl groups of alditol, water molecules and chloride ions form an extensive hydrogen bond network. The FTIRresults indicate that galactitol coordinates to Eu3+ and Tb3+ 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.

Key words: Galactitol, Luminescence spectrum, Lanthanide complex
