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]
