Magnesium polonide (MgPo) is a salt of magnesium and polonium. It is a polonide, a set of very chemically stable compounds of polonium.^[3]

Preparation

Magnesium polonide can be produced by heating a mixture of elemental magnesium and polonium at 300–400 °C.^[1]

Structure

Magnesium polonide has the nickeline (NiAs) structure.^[1]^[3] It is unusual among polonides in not being isomorphous with the corresponding sulfide, selenide and telluride; only mercury polonide (HgPo) shares this property.^[2]
