    Description / Table of Contents: Novel Inorganic Ring Systems. XX. Tricyclic Inorganic Ring Systems with Four and Five Different ElementsThe four ring systems D, E, F and G unknown solong, could be synthesized according to Schema 1. Their structure was confirmed by mass, proton resonance, and infrared spectroscopy. The single compounds are characterized by a deep green colour and an unusually high solubility in indifferent organic solvents.
    Notes: Die vier bisher unbekannten Ringsysteme D, E, F und G konnten nach den Angaben des Schema 1 synthetisiert werden. Ihre Struktur wurde durch Massen-, NMR- und IR-Spektren sowie Röntgenstrukturanalysen sichergestellt. Die einzelnen Verbindungen zeichnen sich durch eine tiefgrüne Farbe und ungewöhnlich hohe Löslichkeit in inerten organischen Lösungsmitteln aus.

    Description / Table of Contents: Novel Inorganic Ring Systems. XIX. Additional Novel Cyclosilazanes and Cyclosiloxazanes Containing N—N Bonds in the Ring StructureAccording to the reaction paths of Schema 1 the compounds I-XIII have been prepared, confirmed in their constitution (Tab. 1-4) and described in their properties (Tab. 1). The seven membered ringsystem Si3N2O2 of compound X and the eight membered ring system Si4N4 (=SiNSi2NSiN2 of compound XIII have been unknown so far. The properties of the 3 isomeric Si4N4-ringsystems (Schema 2) are compared.
    Notes: Auf den Reaktionswegen des Schema 1 wurden die Verbindungen I-XIII dargestellt, in ihrer Struktur aufgeklärt (Tab. 1-4) und in ihren Eigenschaften beschrieben (Tab. 1). Das in X enthaltene siebengliedrige Ringsystem Si3N2O2 und das achtgliedrige Ringsystem Si4N4 (=SiNSi2NSiN2) der Verbindung XIII warden bisher unbekannt. Die Eigenschaften der 3 isomeren Ringsysteme Si4N4 (Schema 2) werden verglichen.
