摘要
在水溶液体系中，用苯羟乙酸直接与碳酸稀土作用，合成了十四种苯羟乙酸稀土配合物。并通过化学分析和元素分析确定了所有配合物的化学组成，试验了配合物的溶解性，测定了配合物在二甲亚砜溶剂中的摩尔电导值。利用红外、核磁共振、紫外以及荧光光谱等对配合物的性质和结构进行了讨论，详细研究了配合物的热行为以及配合物中稀土离子与配位原子的成键性质。
The fourteen complexes of mandelic acid with rare earth elements in aqueous solution have been prepared.The composition of the new complexes has been determined as RE(C_6H_5CHOHCOO)_3 · 2H_2O by chemical and elemental analysis. The solubility in different solvent and morlar conductances were measured.The structures and properties of the complexes were investigated using IR , TGA,￣1 HNMR and Fluorescence techniques. The bonding characters of the complexes are also discussed.
