Chemical compound
Potassium polonide is a chemical compound with the formula K 2 Po . It is a polonide , a set of very chemically stable compounds of polonium.[ 2] [ 3]
Characteristics
Potassium polonide is thermally more unstable and has stronger electron affinity than potassium telluride (K2 Te).[ 2] [ 3]
Production
Potassium polonide may be produced from a redox reaction between polonium hydride and potassium metal:[ 2] [ 3]
H2 Po + 2 K → K2 Po + 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]
