Copper(II) azide is a medium density explosive with the molecular formula Cu(N₃)₂.

Uses

Copper azide is very explosive and is too sensitive for any practical use unless handled in solution.

Preparation

Copper azide can be prepared by a metathesis reaction between water-soluble sources of Cu²⁺ and azide ions. (Spectator ions omitted in reaction below).

Cu²⁺ + 2 N−3 → Cu(N₃)₂

It can be destroyed by concentrated nitric acid to form non-explosive products, these being nitrogen, nitrogen oxides and copper(II) nitrate.
