Hydrazinium azide or hydrazine azide is a chemical compound with formula H5N5 or [N2H+5][N−3]. It is a salt of the hydrazinium cation [N2H+5] and the azide anion N−3. It can be seen as a derivative of hydrazine N2H4 and hydrazoic acid HN3. It is an unstable solid.
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.
