Lithium azide unit cell[1]
Lithium azide is the lithium salt of hydrazoic acid. It is an unstable and toxic compound that decomposes into lithium and nitrogen when heated.
Preparation
It can be prepared by metathesis reaction between sodium azide and lithium nitrate:
- NaN3 + LiNO3 → LiN3 + NaNO3
or lithium sulfate solutions:
- 2 NaN3 + Li2SO4 → 2 LiN3 + Na2SO4[2]
