Azidotetrazolate
Azidotetrazolate CN7− is a highly explosive series of salts and an anion. The ion is made by removing a proton from 5-azido-1H-tetrazole. The molecular structure contains a five membered ring with four nitrogen atoms, and a side azido chain connected to the carbon atom. Several salts exist, but they are unstable and spontaneously explode.[1]
