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: [1]
- 3 Cd(NH2)2 → Cd3N2 + 4 NH3
It can also be produced by thermal decomposition of cadmium azide at 210 °C. [2]
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. [1]
