Characteristics

Potassium polonide is thermally more unstable and has stronger electron affinity than potassium telluride (K2Te).[2][3]

Production

Potassium polonide may be produced from a redox reaction between polonium hydride and potassium metal:[2][3]

H2Po + 2 K → K2Po + H2

It may also be produced by heating potassium and polonium together at 300–400 °C.[1] At higher temperature, this reaction may reverse.

Crystal structure

Like sodium polonide, potassium polonide has the antifluorite structure.[2][3]
