The solid undergoes structural phase transition to a different crystalline arrangement at a pressure of 13 GPa.[2]
Chemistryedit
Hydrazinium azide decomposes explosively into hydrazine, ammonia, and nitrogen gas:[3]
12 N 5H 5 → 3 N 2H 4 + 16 NH 3 + 19 N 2
Crystallization with an equimolar amount hydrazine yields the solid hydrazinium azide hydrazinate, [N 2H+ 5][N− 3]·[N 2H 4], or N 7H 9, as monoclinic crystals. This compound is less hygroscopic and less volatile than pure hydrazinium azide. It decomposes explosively into nitrogen, hydrogen, and ammonia.[4]
At pressure of 40 GPa, hydrazinium azide decomposes yielding a linear nitrogen allotrope N 8 or N≡+N−−N−N=N−−N−+N≡N, that decomposes to ε-N2 below 25 GPa.[2]
