摘　　要：Reaction of SmI2（THF）x with 2 equivalents of NaOAr （Ar = C6H2-tert-Bu3-2,4,6） in THF affords a divalent complex of Sm（OAr）2（THF）yTHF 1 in 90.8% yield. Treatment of 1 with 1,2-dimethoxyethane （DME） leads to the ligand-exchange reaction, and a DME-solvated complex of Sm（OAr）2（DME）2 2 was obtained. Complex 1 crystallizes in monoclinic, space group P21/c with a = 10.366（5）, b = 33.024（15）, c = 16.123（7） A, β = 93.197（8）°, V = 5511 （4） A^3, Z = 4, C52H90O6Sm, Mr = 961.59, Dc = 1.159 g/cm^3, F（000） = 2048,μ（MoKα） = 1.107 mm^-1, R = 0.0844 and wR = 0.1401 for 4694 observed reflections. Complex 2 crystallizes in monoclinic, space group C2/c with a = 27.222（5）, b = 10.6140（19）, c = 17.398（4） A, β = 110.245（3）°, V = 4716.4（16） A^3, Z = 4, C44H78O6Sm, Mr = 853.41, Dc = 1.202 g/cm^3, F（000） = 1808,μ（MoKα） = 1.285 mm^-1, R = 0.0361 and wR = 0.0830 for 5210 observed reflections.Reaction of SmI2（THF）x with 2 equivalents of NaOAr （Ar = C6H2-tert-Bu3-2,4,6） in THF affords a divalent complex of Sm（OAr）2（THF）yTHF 1 in 90.8% yield.
