Magnesium polonide, MgPo, is a chemical compound of magnesium from the group of polonides .

Extraction

Magnesium polonide can be produced by direct reaction of both elements between 300 ° C and 400 ° C.

properties

In contrast to the other polonides , the crystal system of magnesium polonide is not like its telluride , but rather has a hexagonal structure. Otherwise, this can only be observed with mercury (II) polonide . It has the nickel arsenide structure with the space group P 6 ₃ / mmc (space group no. 194) and the lattice parameters a = 4.345  Å and c = 7.077 Å.
