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
