(CH3)4C2(C5H4)2Sm(C5H5)(OC4H8),Mr=499.4,orthorhom-bic,Cc2a,a=11.696(6),b=12.539(5),c=29.432(15)A,V=4316(4)A3,Z=8,Dc=1.54g/cm3,μ(MoKa)=27.8cm-1,F(000)=2024,R=0.077 for 1833 observed reflections.The samarium atom in the molecule is bonded to three cyclopen-tadienyl rings and one oxygen atom of tetrahydrofuran(THF)to form a tetrahedral configuration.The average Sm-C(η5-Cp)distances for the three cyclopentadienyl groups are 2.72(3),2.76(3)and 2.78(3)A,respectively,and the Sm-O bond is 2.53(1)A.
