摘　　要：The complexes of cyclopentadienyl tetramethylethenebridsied dicyclopentadienylsamarium (Ⅲ) tetrahydrofuranates, Me4C2(C5H4)2LnC5H5 (THF) (Ln = Nd, Sm, Gd, Yb) were synthesized and characterized by elemental analysis, IR, 1HNMR, thermogravimetry and MS. The crystal structure of Me4C2(C5H4)2SmC5H5 was determined by X-ray diffraction method. The crystal belongs orthorhombic space group Cc2a. with a =1 . 1696(6) nm, b =1 .2539(5) nm, c = 2.9432(15) nm, V= 4.316 (4) nm3, Z= 8 and Dc = 1 . 54 g . cm-3.The complexes of cyclopentadienyl tetramethylethenebridsied dicyclopentadienylsamarium (Ⅲ) tetrahydrofuranates, Me4C2(C5H4)2LnC5H5 (THF) (Ln = Nd, Sm, Gd, Yb) were synthesized and characterized by elemental analysis, IR, 1HNMR, thermogravimetry and MS.
