摘　　要：Reaction of (ArO)2Sm(THF)4 (ArO = 2,6-di- tert-butyl-4-methylphenolate) with Et2AlCl in THF gives SmCl2 (1) and (ArO)AlEt2(THF) (2) via ligand exchange. Complex 1 reacts with cyclooctatetraene (C8H8) to give [(C8H8)SmCl(THF)2]2(3).Crystal structural determinations show that compl 2 has a monomeric structure,the aluminum atom is coordinated by two carbon atoms and two oxygen atoms,to form a distorted tetrahedron. Complex 3 has a dimeric structure,the samarium atom is coordinated by a cyclooctatetraenyl ring,two chorine atoms and two oxygen atoms,the coordination number of the central metal is 9.Reaction of (ArO)2Sm(THF)4 (ArO = 2,6-di- tert-butyl-4-methylphenolate) with Et2AlCl in THF gives SmCl2 (1) and (ArO)AlEt2(THF) (2) via ligand exchange.
