Organometallic Compounds of the Lanthanides. 88. Monomeric Lanthanide(III) Amides: Synthesis and X-Ray Crystal Structure of [Nd{N(C6H5)(SiMe3)}3(THF)], [Li(THF)2(μ-Cl)2Nd{N(C6H3Me2-2,6)(SiMe3)}2(THF)], and [ClNd{N(C6H3-ipso-Pr2-2,6)(SiMe3)}2(THF)]

A series of lanthanide(III) amides [Ln{N(C6H5)(SiMe3)}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, LnCl3, with LiN(C6H5)(SiMe3). Treatment of NdCl3(THF)2 and LuCl3(THF)3 with the lithium salts of the bulky amides [N(C6H3R2-2,6-)(SiMe3)](1-) (R=Me, iso-Pr) results in the formation of the lanthanide diamides [Li(THF)2(μ-Cl)2Nd{N(C6H3Me2-2,6-)(SiMe3)}2(THF)] (11) and [ClLn{N(C6H3-iso-Pr2-2,6)(SiMe3)}2(THF)] [Ln=Nd (12), Lu (13)], respectively. The (1)H and (13)C-NMR and mass spectra of the new compounds as well as the X-ray crystal structure of neodymium derivatives 3,11 and 12 are discussed.
