Ammonium ozonide is an oxygen rich molecule containing an ammonium cation (NH₄⁺) and an ozonide anion (O₃⁻). Ammonium ozonide, like alkali ozonides, is a red solid. Ammonium ozonide is stable at low temperatures, but it decomposes to ammonium nitrate at temperatures above -70 °C.

Preparation and decomposition

Ammonium ozonide is made by bubbling gaseous ozone through liquid ammonia at -110 °C. This method suffers from a low yield.

:{{chem2 | 12 NH3 + 11 O3 -> 9 NH4O3 + 3 NO2}}

Ammonium ozonide decomposes into ammonium nitrate, oxygen gas, and water. If the above reaction is done at high temperatures, these decomposition products result immediately and no ozonide is formed.

:{{chem2 | 4 NH4O3 -> 2 NH4NO3 + O2 + 4 H2O}}
