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[edit]

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]
