Neue anorganische Ringsysteme. XXII. Neue Spirosilazane der Gerüsttypen Si5N4, Si5N5, Si5N4O und Si7N8

Novel Inorganic Ring Systems. XXII. Novel Spirosilazanes of the Si₅N₄, Si₅N₅, Si₅N₄O, and Si₇N₈ Skeleton We succeeded in preparing the four novel spirosilazane skeletons E , F , G , and H of the composition given in the title. The permethylated compounds of the mentioned systems have been characterized in their chemical and physical properties. The conformation of their structure was possible by elemental analysis and by n.m.r., mass, i.r., and Raman spectra.
