1-Diazidocarbamoyl-5-azidotetrazole, often informally referred to as azidoazide azide, is a heterocyclic inorganic compound with the formula C2N14 It is an extremely sensitive explosive. The C2N14 molecule is a monocyclic tetrazole with three azide groups with a molecular weight of 220.16 g.mol⁻¹. It has a molecular equilibrium between a closed and an open form, isocyanogen tetraazide which has been known since 1961, the latter being quickly cyclized to the cyclic tetrazole form (C2N14) at room temperature. Despite rumors and videos carrying exaggerated information over this compound and despite rectifications, C2N14 is not the world's most sensitive compound; there are other contact explosi...
