Ammonium ozonide


Ammonium ozonide is an oxygen rich compound with the formula. This salt consists of ammonium cations and ozonide anions. Ammonium ozonide, like alkali ozonides, is a deep 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.
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.
