    Description / Table of Contents: Tetramethyldisilane-1,2-diyl bridged Dicyclopentadienyl and Diindenyl Metal Dichlorides of the Group 4 Metals - Crystal Structure of Dicyclopentadienyl and diindenyl metal dichlorides of the type Cp′—SiMe2SiMe2—Cp′MCl2 (Cp′ = C5H4, M = Ti (1), Zr (2), Hf (3); Cp′ = C9H7, M = Zr (4), Hf (5)) were synthesized and characterized by means of their 1H, 13C, 29Si-n.m.r., MS, and IR spectra. The crystal structure of 2 was determined.
    Notes: Dicyclopentadienyl- und Diindenylmetalldichloride des Typs Cp′—Me2Si—Me2Si—Cp′MCl2(Cp′ = C5H4; M = Ti(1), Zr (2), Hf (3); Cp′ = C9H7; M = Zr (4), Hf (5)) wurden synthetisiert und mittels ihrer 1H-, 13C- und 29Si-NMR-Spektren sowie MS- und IR-Spektren charakterisiert. Die Kristallstruktur von 2 wurde ermittelt.

    Description / Table of Contents: 2,6-Bis(methylenecyclopentadienyl)-pyridine-zirconocene and -hafnocene Dichloride; Formation and Crystal Structure of [C5H3N-2,6-(CH2—C5H4)2Zr(Cl)(OH2)[ZrCl6]]Pyridine bridged metallocene dichlorides of type C5H3N-2,6-(CH2—C5H4)2MCl2 (M = Zr (2), Hf (5)) were synthesized. The presence of N → Zr interaction favours the formation of zirconocene cations. Traces of water cause the formation of the salt-like compound [C5H3N-2,6-(CH2—C5H4)2Zr(Cl)(OH2)]2[ZrCl6] 4 from 2. The new compounds were characterized by 1H n.m.r., and mass spectroscopy. The X-ray crystal structure of 4 shows discrete cations and anions which are connected by H-bridges.
    Notes: Pyridinverbrückte Metallocendichloride des Typs C5H3N-2,6-(CH2—C5H4)2MCl2 (M = Zr (2), Hf (5)) wurden synthetisiert. Aufgrund einer N → Zr-Wechselwirkung wird die Bildung von Zirconocen-Kationen begünstigt. So entsteht bei der Einwirkung von Feuchtigkeit auf 2 die ionisch aufgebaute Verbindung [C5H3N-2,6-(CH2—C5H4)2Zr(Cl)(OH2)]2[ZrCl6] 4. Die Verbindungen wurden 1H-NMR und MS-spektroskopisch charakterisiert. Die Kristallstruktur von 4 läßt eine Verknüpfung der Kationen und Anionen über H-Brückenbindungen erkennen.
