摘要
A dimeric yttrium complex [Y(C5Me4SiMe3){μ-O(CH2)3CH3}{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 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 com-plex 1 was a symmetric dimer,and the center metal Y3+ was six-coordinated by one nitrogen atom from the amide group,two bridging oxy-gen atoms from the O(CH2)3CH3 groups,and one cyclopentadienyl ring in 5-fashion to adopt a distorted tetrahedron geometry.The forma-tion of complex 1 was postulated to be a result from C-O bond cleavage reaction of THF.
