Magnesium ozonide


Magnesium ozonide is a compound with the formula MgO3. Much like other ozonides, it is only stable at low temperatures. Unlike other ozonide compounds, magnesium ozonide is white rather than the typical red colour.

Preparation

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

Magnesium bisozonide

Magnesium is also known to form bisozonide complexes, containing Mg2 complexed with argon or carbon monoxide, in an argon matrix.
