D－葡萄糖与氯化稀土配合物的合成及红外光谱研究

Synthesis and FTIR Spectroscopy Study of the Rare Earth Complexes with D-Glucose

以非水溶剂为介质合成了Ｄ－葡萄糖、氯化稀土、吡啶的混配多元配合物，并进行了元素分析和红外光谱测定。研究结果表明，Ｄ－葡萄糖和溶剂吡啶同时参与了配位，该配合物的组成为：Ｌｎ（Ｃ_６Ｈ_（１２）Ｏ_６）（Ｃ_５Ｈ_５Ｎ）Ｃｌ_３（Ｌｎ＝Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｓｍ等）．本文还对配合物的可能结构进行了讨论．

Rare earth complexes with D-glucose were successfully prepared in pyridine and characterized by elementary analysis and FTIR measurements. The experimental results indicate that each rare earth ion is coordinated to two glucose molecules and one pyridine molecule. The composition of rare earth complexes with D-glucose is Ln(C6H12O6)·(C5H5N)Cl3. The potential structure of this compound is discussed.
