Sodium polonide is an chemical compound with the formula Na2Po. It is a polonide, a set of very chemically stable compounds of polonium.[2][3]
Production
Sodium polonide may be produced from an acid–base reaction between aqueous hydrogen polonide (hydropolonic acid) and sodium metal:[2][3]
- H2Po + 2 Na → Na2Po + H2
It may also be produced by heating sodium and polonium together at 300–400 °C.[1]
Crystal structure
Sodium polonide has the antifluorite structure.[2][3]
