Silicon Tetraazide (SiN12)

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. A further coordination to a six-fold coordinated structure such as a hexaazido silicide [Si(N3)6]2−[4] or as an adduct with bicationic ligands Si(N3)4L2 will result in relatively stable, crystalline solids that can be handled at room temperature. Silicon tetraazide is a white crystalline compound that will detonate at even 0 °C. The pure compound, and also silicon chloride triazide and silicon dichloride diazide contaminated samples, can detonate spontaneously without clear cause. The compo...View all
