Polonide

Chemical compound

A polonide is a chemical compound of the radioactive element polonium with any element less electronegative than polonium. Polonides are usually prepared by a direct reaction between the elements at temperatures of around 300–400 °C. They are amongst the most chemically stable compounds of polonium, and can be divided into two broad groups:ionic polonides, which appear to contain the Po2− anion; intermetallic polonides, in which the bonding is more complex.
