    Description / Table of Contents: Eine Untersuchung zur Struktur von Tryllers und Schmitz' Verbindungen sowie von verwandten SubstanzenNMR-spektroskopische Untersuchungen zeigen, daß Tryllersche und Schmitzsche Verbindungen Furoxan- (3) beziehungsweise 1,4,2,5-Dioxadiazin-Struktur (11) besitzen. NMR- und röntgenkristallographische Untersuchungen zeigen, daß es sich bei den durch Einwirkung von Stickstoffetroxid und 5proz. Natronlauge auf die Tryllersche Verbindung erhaltenen Produkten um Furazano[3,4-d]pyridazin-1,5,6-trioxid (5) beziehungsweise Furazano[3,4-d]pyridazin-5,6-dioxid (8) handelt. Mit den gleichen Methoden wird auch gezeigt, daß dem durch Einwirkung von Stickstofftetroxid auf die Schmitzsche Verbindung erhaltenen Produkt die 1,4,2,5-Dioxadiazin-Struktur 12 zugeordnet werden kann.
    Notes: NMR spectroscopic studies show that Tryller's and Schmitz's compounds have furoxan (3) and 1,4,2,5-dioxadiazine (11) structures, respectively. Combined NMR spectroscopy and X-ray crystallography show that the products obtained by action of dinitrogen tetroxide and 5% sodium hydroxide on Tryller's compound have furazano[3,4-d]pyridazine 1,5,6-trioxide and furazano[3,4-d]pyridazine 5,6-dioxide structures 5 and 8, respectively. They also show that the product obtained by action of dinitrogen tetroxide on Schmitz's compound has a dinitroethyl-1,4,2,5-dioxadiazine structure 12.
