Zinc azide (Zn(N₃)₂) is an inorganic compound composed of zinc and azide. It is a white, explosive solid. It is a coordination polymer, which crystallizes in three polymorphs, all of which feature tetrahedral zinc centers and bridging azide ligands. They are prepared by the protonolysis of diethyl zinc with hydrazoic acid:^[1]

Zn(C₂H₅)₂ + 2 HN₃ → Zn(N₃)₂ + 2 C₂H₆
