Organometallic Compounds of the Lanthanides, 90[1]. - [(tert-Butylcyclopentadienyl)dimethyl-(tetramethylcyclopentadienyl)silane] Complexes of Lanthanum, Neodymium, and Lutetium[(tBuC5H3)SiMe2(C5Me4)]Li2 (1) reacts with LnCl3 (Ln = La, Lu) in THF to yield [(tBuC5H3)SiMe2(C5Me4)]Ln(μ-Cl)2Li-(OEt2)2 [Ln = La (3a), Lu (3c)]. The reactions of LnCl3 (Ln = La, Nd) with [(tBuC5H3)SiMe2(C5Me4)]Na2 (2) and (C5Me4H)Na in THF result in the formation of the chiral tris(cyclopentadienyl) complexes [(tBuC5H3)SiMe2(C5Me4)]Ln-(C5Me4H)(THF) [Ln = La (4a), Nd (4b)]. The 1H- and 13CNMR and mass spectra of the new compounds as well as the X-ray crystal structure of 4a are discussed.
