摘要：

Unsolvated hydride derivatives [Me2Si- (2-Me-C9H5)2LnH] (Ln=Y, Ho) are available from ansa-lanthanidocene complexes rac-[{Me2Si(2-Me-C9H5)2} Ln{N(SiHMe2)2}] by utilizing a novel [N(SiHMe2)2]/[H] transformation inititated by diisobutylaluminumhydride (DIBAH; see scheme; R=SiHMe2). The molecular structure of the THF adduct reveals a flyover" dimer of composition [{Y(thf)}2{μ2-[(Η5-2-ME- C9H5)SiMe2(Η5-2- Me-C9H5)]}2(μ2- H)2]."
