 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.Despite this, a crystal structure of bromine azide has been obtained using a miniature zone-melting procedure with focused infrared laser radiation.
