The crystal structure of the title compound in which DME=Dimethoxyethane was determined using x-ray diffractometer. The complex crystallizes in monoclinic space group P21/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 and refined 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 atems of DME. The Sm-Cl distances are in the range 2.647-2.674Å. The Sm-O distances are in the range 2.465-2.504Å.
