Preparation
Magnesium polonide may be produced by heating elemental magnesium and polonium together at 300–400 °C.[1]
Structure
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]
gollark: "Kura Technologies" apparently managed some very impressive things with accursed physicsy optics, but I don't think they're widely available now or have had proper external reviews.
gollark: I'm mostly interested in AR, since a better interface for looking at internet things on the go than my phone would be very convenient.
gollark: Yet most people in developed countries apparently have smartphones now.
gollark: Presumably if they get particularly popular, they'll be available on the technically-worse-but-better-looking-than-buying-it-outright phone-style contracts.
