    Description / Table of Contents: Aromatic Complexes of Metals, CXVCXIV. Mitteil.: E. O. Fischer und R. J. J. Schneider, Chem. Ber. 103, 3684 (1970). Über Di-π-cyclopentadienyl-μ-π-cyclopentadien-dimetall-Komplexe des Palladiums, Nickels und Platins, „Tetracyclopentadienyl-dipalladium“ und π-Cyclopentadienyl-π-(2-methyl-1-acetyl-allyl)-palladium. On Di-π-cyclopentadienyl-μ-π-cyclopentadienedimetal Complexes of Palladium, Nickel, and Platinum as well as on „Tetracyclopentadienyldipalladium“ and π-Cyclopentadienyl-π-(2-methyl-1-acetylallyl)palladiumMetal halides MX2 = PdBr2, NiI2 yield with alkali cyclopentadienides and cyclopentadiene a new diamagnetic type of compounds according to An analogously composed platinum complex was detected too. Spectroscopic investigations support a molecular structure with a metal-metal bond, two π-bonded C5H5-rings and a π-bonded C5H6-ring as bridge in a manner that the compounds can be described as di-π-cyclopentadienyl-μ-π-cyclopentadienedimetal complexes. - Variation of the reaction conditions led to Pd2C20H20 mixed with Pd2(C5H5)2C5H6. Pd2C20H20 was proved by mass spectroscopy and so the question of a „tetracyclopentadienyldipalladium“ is settled. It should, however, exist as di-π-cyclopentadienyl-μ-π-(5-cyclopentadienylcyclopentadiene)dipalladium. According to violet, diamagnetic π-cyclopentadienyl-π-(2-methyl-1-acetylallyl)palladium was obtained.
    Notes: Metallhalogenide MX2 = PdBr2, NiJ2 ergeben mit Alkalicyclopentadieniden und Cyclopentadien einen neuen diamagnetischen Verbindungstyp nach Ein analog zusammengesetzter Platin-Komplex konnte ebenfalls nachgewiesen werden. Spektroskopische Untersuchungen sprechen für einen Molekülaufbau mit Metall-Metall-Bindung, zwei π-gebundenen C5H5-Ringen und π-gebundenem C5H6 als Brücke, so daß die Verbindungen als Di-π-cyclopentadienyl-μ-π-cyclopentadien-dimetall-Komplexe aufzufassen sind. - Durch Änderung der Reaktionsbedingungen im Gemisch mit Pd2(C5H5)2C5H6 entstehendes Pd2C20H20 ließ sich massenspektroskopisch sichern und damit die Frage nach einem „Tetracyclopentadienyl-dipalladium“ beantworten, das jedoch als Di-π-cyclopentadienyl-μ-π-(5-cyclopentadienyl-cyclopentadien)-dipalladium vorliegen dürfte. - Nach entsteht violettes, diamagnetisches π-Cyclopentadienyl-π-(2-methyl-l-acetyl-allyl)-palladium.
