Silver nitride is an explosive chemical compound with symbol Ag3N. It is a black, metallic-looking[3] solid which is formed when silver oxide or silver nitrate[4] is dissolved in concentrated solutions of ammonia, causing formation of the diammine silver complex which subsequently breaks down to Ag3N. The standard free energy of the compound is about +315 kJ/mol, making it an endothermic compound which decomposes explosively to metallic silver and nitrogen gas.
