Magnesium polonide (MgPo) is a salt ofmagnesium andpolonium. It is apolonide, a set of very chemically stable compounds of polonium.[3]
Magnesium polonide can be produced by heating a mixture of elemental magnesium and polonium at 300–400 °C.[1]
Magnesium polonide has thenickeline (NiAs) structure.[1][3] It is unusual amongpolonides in not beingisomorphous with the correspondingsulfide,selenide andtelluride; onlymercury polonide (HgPo) shares this property.[2]
