Silicon tetraazide is a thermally unstable binary compound of silicon and nitrogen with a nitrogen content of 85.7% (by molar mass). This high-energy compound combusts spontaneously and can only be studied in a solution.[1][2][3] A further coordination to a six-fold coordinated structure such as a hexaazidosilicate ion [Si(N3)6]2−[4] or as an adduct with bidentate ligands Si(N3)4·L2[2] will result in relatively stable, crystalline solids that can be handled at room temperature.
