CsN3 adopts the same structure as KN3, RbN3, and TlN3, crystallizing in a tetragonal distorted caesium chloride structure where each azide ion coordinates to eight metal cations, and each metal cation coordinates to eight terminal N centers.[2] When heated to 151°C, it transitions to a cubic structure.[3]
The thermal decomposition of CsN3in vacuo can be used as a method of generating high purity caesium metal:[5]
2 CsN3 → 2 Cs + 3 N2
