Lithium polonide is a chemical compound with the formula Li2Po. It is a polonide, a set of very chemically stable compounds of polonium.{{Greenwood&Earnshaw1st|page=899}}{{citation | last = Moyer | first = Harvey V. | contribution = Chemical Properties of Polonium | pages = 33–96 | title = Polonium | url = http://www.osti.gov/bridge/servlets/purl/4367751-nEJIbm/ | editor-last = Moyer | editor-first = Harvey V. | id = TID-5221 | doi = 10.2172/4367751 | year = 1956 | location = Oak Ridge, Tenn. | publisher = United States Atomic Energy Commission| doi-access = free }}.

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:

:H2Po + 2 Li → Li2Po + H2

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

Crystal structure

Like sodium polonide, lithium polonide has the antifluorite structure.
