稀土有机化合物的研究是当前十分活跃的一个领域.有关氯化稀土吡啶配合物的合成早已有报道,但系统地分离出具有LnCl_3·nPy配合物的工作是最近才完成的.迄今尚未见到关于这类配合物晶体结构的报道.我们首先用X射线单晶衍射的方法,测定了EuCL_3·4Py的晶体结构,揭示了这类配合物的结构特征.
The study of rare earth organic compounds is a very active one now.Relation has been reported on the synthesis of rare earth pyridine complexes, but the systematic isolation of complexes with LnCl_3.nPy has only recently been completed. The crystal structure of these complexes was reported.We first determined the crystal structure of EuCL_3.4Py by single-crystal X-ray diffraction and revealed the structural characteristics of these complexes.
