}} Silicon tetraazide is a thermally unstable binary compound of silicon and nitrogen with a nitrogen content of 85.7%. This high-energy compound combusts spontaneously and can only be studied in a solution 〔Wilberg, E.; Michaud, H.: Z. Naturforsch. B 9 (1954) S. 500.〕〔Portius, P.; Filippou, A.C.; Schnakenburg, G.; Davis, M.; Wehrstedt, K.-D.: ''Neutrale Lewis-Basen-Addukte des Siliciumtetraazids'' in Angew. Chem. 122 (2010) S. 8185–8189, 〕〔Gmelins Handbook of Inorganic Chemistry, 8th Edition, ''Silicon'' Supplement Volume B4, Springer-Verlag 1989, S. 46.〕 A further coordination to a six-fold coordinated structure like a hexaazido silicide ()2− 〔Filippou, A.C.; Portius, P.; Schnakenburg, G.: ''The Hexaazidosilicate(IV) Ion: Synthesis, Properties, and Molecular Structure'' in J.
