Copper(II) azide is a medium density explosive with the molecular formula {{chem2|Cu(N3)2}}.

__TOC__

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 {{chem2|Cu(2+)}} and azide ions. (Spectator ions omitted in reaction below).

:{{chem2|Cu(2+) + 2 N3− → 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.
