Magnesium polonide (MgPo) is a salt of magnesium and polonium. It is a polonide, a set of very chemically stable compounds of polonium.[2]

Preparation[edit]

Magnesium polonide may be produced by heating elemental magnesium and polonium together at 300–400 °C.[1]

Structure[edit]

Magnesium polonide has the nickeline (NiAs) structure with lattice parameters a = 434.5 pm and c = 707.7 pm.[1][2] It is unusual among polonides in not being isomorphous with the corresponding sulfide, selenide and telluride; only mercury polonide (HgPo) shares this property.[3]
