Cadmium nitride is a nitride of cadmium with the chemical formula Cd₃N₂.

Preparation

Cadmium nitride can be produced by thermal decomposition of cadmium amide at 180 °C:

3 Cd(NH₂)₂ → Cd₃N₂ + 4 NH₃

It can also be produced by thermal decomposition of cadmium azide at 210 °C.

Properties

Cadmium nitride is a black solid that decomposes on contact with water and air. It will explode when reacting with dilute acids or alkalis. It is a crystal of inverse manganese(III) oxide structure with lattice constant a = 1079 pm.
