摘要
The reaction of Ln[N(SiMe3)2]3 with K under N2 in THF forms the dinitrogen complexes {[(Me3Si)2N]2(THF)Ln}2(μ-η2:η2-N2) (Ln = Y, Ho, Tm, and Lu) previously available only for lanthanides with highly reducing divalent states, that is, Tm, Dy, and Nd. The Y and Lu complexes are the first diamagnetic complexes of this type. The Ln2N2 moiety is planar, and the 1.268(3) and 1.285(4) Å NN distances in these complexes are consistent with the presence of (N2)2. Copyright © 2004 American Chemical Society.
