Abstract

Abstract: The crystal structure of the title compound in which DME = Dimethoxyethane wasdetermined using x-ray diffractometer. The complex crystallizes in monoclinic space group P2_1/a with Z = 4. Lattice parameters are: a = 13.547(8), b = 8.607(4), c = 16.029(9)Å,β= 90.35(5)°. The crystal structure was determined by Patterson and Fourier techniques andrefined by least-squares to a final value R = 0.0443. The samarium(Ⅲ) ion is 7-coordinate,being bonded to three chlorine atoms, two oxygen atoms of two THF and two oxygen atemsof DME. The Sm-Cl distances are in the range 2.647-2.674Å. The Sm-O distances are inthe range 2.465-2.504Å.

Key words: Complex of samarium with dimethoxyethane, Crystal structure, x-Ray, diffractometry
