摘要：
A series of lanthanide(III) amides [Ln{N(C6H5). (SiMe(3))}(3)(THF)(x)] [Ln = Y (1), La (2), Nd (3), Sm (4), Eu (5), Tb (6), Er (8), Yb (9), Lu (10)] could be prepared by the reaction of lanthanide trichlorides, LnCl(3) with LiN(C6H5)(SiMe(3)). Treatment of NdCl3(THF)(2) and LuCl3(THF)(3) with the lithium salts of the bulky amides [[N(C(6)H(3)R(2)-2,6)(SiMe(3))] - (R = Me, iso-Pr) results in the formation of the lanthanide diamides[Li(THF)(2)(mu-Cl)(2)Nd{N(C(6)H(3)Me(2)-2,6)(SiMe(3))}(2)(THF)] (11) and [ClLn{N(C6H3-iso-Pr-2-2,6)(SiMe(3))}(2)(THF)] [Ln = Nd (12), Lu (13)], respectively. The H-1- and C-13-NMR and mass spectra of the new compounds as well as the X-ray crystal structures of the neodymium derivatives 3, 11 and 12 are discussed.
