Chemical compound
Caesium ozonide is an oxygen-rich chemical compound of caesium, with the chemical formula CsO3. It consists of caesium cations Cs+ and ozonide anions O−3. It can be formed by reacting ozone with caesium superoxide:[2][3]
CsO2 + O3 → CsO3 + O2
The compound reacts strongly with any water in the air forming caesium hydroxide.[3]
4 CsO3 + 2 H2O → 4 CsOH + 5 O2
If heated to between 70 and 100 °C, caesium ozonide will quickly decompose to caesium superoxide (CsO2).[3] In fact, the compound is metastable to decomposition into caesium superoxide, slowly decomposing at room temperature, but can remain intact for months if stored at −20 °C.[4]
Above around 8 °C, the crystal structure is of the caesium chloride type, with the ozonide ion in place of the chloride ion. At lower temperatures, the crystal structure changes to a structure identical to rubidium ozonide (RbO3), with space group P21/c.[2]
