Bromine azide

Bromine azide is an explosive inorganic compound with the formula BrN3. It has been described as a crystal or a red liquid at room temperature. It is extremely sensitive to small variations in temperature and pressure, thus extreme caution must be observed when working with this reagent. This property of bromine azide has led to difficulty in discerning its crystal structure, with explosions occurring at Δp ≥ 0.05 Torr and also upon crystallization. Wikipedia
