摘要：

A dimeric yttrium complex [Y(C5Me4SiMe3){mu-O(CH2)(3)CH3}{N(SiHMe2)(2)}](2) (1) was isolated as one of the byproducts from the reaction of Y{N(SiHMe2)(3)}(3)(THF)(2) with C5Me4HSiMe3 in 1:1.1 molar ratio in toluene at 100 degrees C for 2 d. Complex 1 was characterized by elemental analysis, NMR spectroscopy, FT-IR spectroscopy, and X-ray single crystal structure analysis. X-ray diffractions revealed that complex 1 was a symmetric dimer, and the center metal Y3+ was six-coordinated by one nitrogen atom from the amide group, two bridging oxygen atoms from the O(CH2)(3)CH3 groups, and one cyclopentadienyl ring in eta(5)-fashion to adopt a distorted tetrahedron geometry. The formation of complex 1 was postulated to be a result from C-O bond cleavage reaction of THF.
