Ammonium azide is ionic, meaning it is a salt consisting of ammonium cations [NH 4] + and azide anions N − 3, therefore its formula is [NH 4] + [N 3] −. It is a structural isomer of tetrazene . Ammonium azide contains about 93% nitrogen by mass.
Ammonium bifluoride, as its name indicates, contains an ammonium cation ([NH 4] +), and a bifluoride (or hydrogen difluoride) anion ([HF 2] −).The triatomic bifluoride anion features a strong three-center four-electron bond with a bond energy greater than 155 kJ/mol, [2] and an H-F length of 114 pm.
