| Abstract
| - Anhydrous lanthanide(III) chlorides (Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb) react with 3 equiv of lithium2,2,5,5-tetramethyl-2,5-disila-1-azacyclopentanide, in THF or Et2O to affordthe monomeric four-coordinate heteroleptic ate complexes (Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy (5), Ho (6), Er (7), Tm (8), Yb (9)), whose solid-state structures weredetermined by the single-crystal X-ray diffraction technique. All complexes additionally were characterized bymelting point determination, elemental analyses, and mass spectrometry.
- The preparation and structural characterization of a series of lanthanide tris(amide)·LiCl ate compounds are presented.
