Metallorganische Verbindungen der Lanthanoide. 113. [(tert‐Butylcyclopentadienyl)(cyclopentadienyl)dimethylsilan]‐Komplexe ausgewählter Lanthanoide

1996 
Die Reaktion von [Me2Si(C5H4)(tBuC5H3)]Li2 mit LnCl3 (Ln = Y, Nd, Sm, Lu) in THF fuhrt zu den chiralen, dimeren Komplexen [Me2Si(C5H4)(tBuC5H3)]Ln(μ-Cl)2Li-(THF)(Et2O) [Ln = Y (1), Nd (2), Sm (3), Lu (4)]. Die 1H-, 13C-NMR- und Massenspektren der neuen Verbindungen sowie die Rontgenstrukturanalysen von 2 a und 3 a werden diskutiert. Organometallic Compounds of the Lanthanides. 113. [(tert-Butylcyclopentadienyl)(cyclopentadienyl)dimethylsilane] Complexes of selected Lanthanides The reaction of [Me2Si(C5H4)(tBuC5H3)]Li2 with LnCl3 (Ln = Y, Nd, Sm, Lu) in THF results in the formation of the chiral, dimeric complexes [Me2Si(C5H4)(tBuC5H3)]Ln(μ-Cl)2Li(THF)(Et2O) [Ln = Y (1), Nd (2), Sm (3), Lu (4)]. The 1H-, 13C-NMR- and the mass spectra of the new compounds as well as the X-ray crystal structures of 2 a and 3 a were discussed.
