Lithium polonide is a chemical compound with the formula Li2Po. It is a polonide, a set of very chemically stable compounds of polonium.[2][3]

Production[edit]

Lithium polonide may be produced from a redox reaction between aqueous hydrogen polonide (hydropolonic acid) 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[edit]

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