Sodium ozonide (NaO3) is an oxygen-rich compound ofsodium. As an ozonide, it contains theozonide anion (O−3).
Some experiments report creating sodium ozonide by applying ozone tosodium hydroxide,[2] but the substance was not pure, and the claimed stability at room temperature was contradicted by other reports.[3] This is in contrast topotassium ozonide,rubidium ozonide, andcaesium ozonide, which can be synthesized applying ozone directly to the metal. Instead, it is made inammonia solution usingion exchange andcryptands.[1][4]
The compound is unstable at room temperature and decomposes at −10 °C tosodium superoxide andoxygen.[5]
However, the compound can be stored for months at −18 °C.[1]
