3Zn(NH₂)₂ → Zn₃N₂ + 4NH₃

It can also be formed by heating zinc to 600 °F in a current of ammonia; the biproduct is hydrogen gas. [cite book

3Zn + 2NH₃ → Zn₃N₂ + 3H₂

Zinc nitride reacts violently with water to form ammonia and zinc oxide.

Zn₃N₂ + 3H₂O → 3ZnO + 2NH₃

It is soluble in hydrochloric acid [cite book
