Hydrazinium azide or hydrazine azide is a chemical compound with formula H5N5 or [N2H5][N3]. It is an unstable white solid. It consists of hydrazinium cations [N2H5]+ and azide anions [N3]−. It is the hydrazine salt of hydrazoic acid.
When very pure, it is insensitive to ordinary levels of shock or impact and only decomposes slowly when heated, but less pure forms tend to explode when heated to a bit over 100 °C (212 °F) or when heated too rapidly.[1]
The solid undergoes structural phase transition to a different crystalline arrangement at a pressure of 13 GPa (130,000 atm).[2]
Preparation
Hydrazinium azide was first prepared by neutralizing hydrazoic acid with hydrazine hydrate.[1]
