摘要： 合成了钐与磷酸二甲酯的配合物,该配合物的组成为Sm[(CH3O)2PO2]3,测定了该配合物的红外和拉曼光谱。x射线单晶衍射法测定配合物的晶体属单斜晶系,P21/c空间群,α=10.434(4)Å,b=16.541(3)Å,c=10.804(4)Å,β=111.75(3)°,V=1731.7(9)Å3,Z=4。钐与6个氧原子配位,每2个相邻的钐原子通过双“O-P-O”桥相连接,形成奇特的“双桥24元环”的环套环网状结构。钐氧配位多面体为稍微扭曲的正八面体。

Abstract: The title. complex has been synthesized and characterized by elemental analysis, FT-IR,Raman spectrometric analysis and X-ray diffractometry. The crystal of the complex is monoclinic with space group P21/c and a=10.434(4),b=16.541(3),C=10.804(4)Å,β=111.75(3)°, V=1731.7(9)Å3 for Z=4. Dimetbyl phosphate anions coordinate with samarium atoms through double O-P-O bridges to form a Epecial network of ring-linking-ring, each of which consists of twenty-four atoms. The coordination number of Sm is six,and the coordinate polyhedron about Sm is a slightly distorted octahedron.

Key words: Complex of samarium with dimethyl phosphate, Crystal structure, Vibration spectrometry
