Potassium polonide is a chemical compound with the formula K2 Po. It is a polonide, a set of very chemically stable compounds of polonium. [2] [3]
Potassium polonide is thermally more unstable and has stronger electron affinity than potassium telluride (K2Te). [2] [3]
Potassium polonide may be produced from a redox reaction between polonium hydride and potassium metal: [2] [3]
It may also be produced by heating potassium and polonium together at 300–400 °C. [1] At higher temperature, this reaction may reverse.
Like sodium polonide, potassium polonide has the antifluorite structure. [2] [3]
