Magnesium ozonide is a compound with the formula Mg O ₃. Much like other ozonides, it is only stable at low temperatures. ^[1] Unlike other ozonide compounds, magnesium ozonide is white rather than the typical red colour. ^[2]

Preparation

Magnesium ozonide can be made by passing a dilute mixture of ozone in liquid nitrogen and over magnesium at -259 °C: ^[1]

O₃ + Mg → MgO₃

Magnesium bisozonide

Magnesium is also known to form bisozonide complexes, containing Mg(O₃)₂ complexed with argon or carbon monoxide, in an argon matrix. ^[3]
