摘要：

Neutral tris(trimethylsilylmethyl) complexes [Ln(CH(2)SiMC(3))(3)(L)] (Ln = Sc (1), Lu (2)) and cationic bis(trimethylsilylmethyl) complexes [Ln(CH(2)SiMe(3))(2)(L)(THF)](+)[BPh(4)](-), (Ln = Sc (3), Lu (4)) that contain bis(2-methoxyethyl)(trimethylsilyl)amine (L = Me(3)SiN(CH(2)-CH(2)OMe)(2)) as a neutral, tridentate ligand were synthesized and characterized by NMR spectroscopy. X-ray structural analysis was performed for the scandium complex 1 and exhibited a distorted octahedral coordination geometry with a facially arranged ligand at the neutral scandium center. NMR spectroscopy corroborated the coordination of the tertiary amine function of the ligand to the metal. Complexes 3 and 4 expand the still limited range of cationic rare-earth metal alkyl complexes with known neutral, multidentate ligands. (c) 2006 Elsevier B.V. All rights reserved.
