Lithium polonide is a chemical compound with the formula Li ₂ Po. It is a polonide, a set of very chemically stable compounds of polonium. ^{[2] [3]}

Production

Lithium polonide may be produced from a redox reaction between aqueous polonium hydride and lithium metal ^{[2] [3]} or from an acid-base reaction of H₂Po with strong lithium-containing bases:

H₂Po + 2 Li → Li₂Po + H₂

It may also be produced by heating lithium and polonium together at 300–400 °C. ^[1]

Crystal structure

Like sodium polonide, lithium polonide has the antifluorite structure. ^{[2] [3]}
