Magnesium polonide

Magnesium polonide is a salt of magnesium and polonium. It is a polonide, a set of very chemically stable compounds of polonium.

Preparation

Magnesium polonide can be produced by heating a mixture of elemental magnesium and polonium at 300–400 °C.

Structure

Magnesium polonide has the nickeline structure. It is unusual among polonides in not being isomorphous with the corresponding sulfide, selenide and telluride; only mercury polonide shares this property.
