Lithium polonide
Lithium polonide is a chemical compound with the formula Li2Po. It is a polonide, a set of very chemically stable compounds of polonium.
Production
Lithium polonide may be produced from a redox reaction between aqueous polonium hydride and lithium metal or from an acid-base reaction of H2Po with strong lithium-containing bases:It may also be produced by heating lithium and polonium together at 300–400 °C.
