Potassium polonide

Potassium polonide is a chemical compound with the formula K<sub>2</sub>Po. 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 (K<sub>2</sub>Te).

Production

Potassium polonide may be produced from a redox reaction between polonium hydride and potassium metal:

H<sub>2</sub>Po + 2 K → K<sub>2</sub>Po + H<sub>2</sub>

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.
