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 N3 → Cu(N3)2

It can be destroyed by nitric acid to form non-explosive products:

Cu(N3)2 + 2HNO3 → 3N2 + 2NO2 + Cu(OH)2
