Potassium polonide


Potassium polonide is a chemical compound with the formula K2Po. It is a polonide, a set of very chemically stable compounds of polonium.

Characteristics

Potassium polonide is thermally more unstable and has stronger electron affinity than potassium telluride.

Production

Potassium polonide may be produced from a redox reaction between polonium hydride and potassium metal:
It may also be produced by heating potassium and polonium together at 300–400 °C. At higher temperature, this reaction may reverse.

Crystal structure

Like sodium polonide, potassium polonide has the antifluorite structure.
