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.
