Zinc nitride (Zn3N2) is an inorganic compound of zinc and nitrogen. In pure form, it is cubic in structure.[1][2]

Chemical properties[edit]

Zinc nitride can be obtained by thermally decomposing zincamide (zinc diamine)[3] in an anaerobic environment, at temperatures in excess of 200 °C. The by-product of the reaction is ammonia.[4]

3Zn(NH2)2 → Zn3N2 + 4NH3

It can also be formed by heating zinc to 600 °C in a current of ammonia; the by-product is hydrogen gas.[3][5]

3Zn + 2NH3 → Zn3N2 + 3H2

Zinc nitride reacts violently with water to form ammonia and zinc oxide.[3][4]

Zn3N2 + 3H2O → 3ZnO + 2NH3

It is soluble in hydrochloric acid[6] and "reversibly reacts with lithium electrochemically".[7] Like magnesium nitride (Mg3N2) and lithium nitride (Li3N), it has a high melting point.[8]
