Final Report Abstract

Das Diffraktometer wird für Einkristalle von metallorganischen und organischen Verbindungen eingesetzt, die insbesondere in den Arbeitskreisen Anwander, Bettinger, Kunz, Mayer, Nachtsheim, Schnepf, Sirsch, Wesemann und Ziegler synthetisiert werden. Die Forschungsgebiete liegen im Bereich von neuen Carbenliganden und Metallorganischen Übergangsmetall- und Lanthanoidkomplexen, die teilweise als homogene Katalysatoren (Olefinpolymerisation, Epoxidisomerisierung) dienen sowie von neuen hochreaktiven Zinn-Verbindungen und metalloiden Clustern der 4. Hauptgruppe und binärer subvalenter Halogenide. Insbesondere die Cu-Quelle kommt bei der Vermessung von Einkristallen neuer Carbenliganden, bor- und stickstoffhaltigen cyclischen Verbindungen und Acenderivaten zum Einsatz.
