Polonium dichloride dibromide with the formula PoCl2Br2 is a possible but poorly characterized interhalogen compound, which is not a common or stable chemical. It is predicted to form when polonium dichloride reacts with bromine, and evidence for its existence from X-ray powder photography [2] is weak, according to the Journal of the Chemical Society
Synthesis and properties Formation: Reaction with bromine vapor at room temperature forms a salmon-pink product that is likely polonium dichloride dibromide.

Characterization

X-ray powder photography has been used to analyze the product, but the results were too poor to definitively prove the existence of a new compound, notes The Royal Society of Chemistry.

Comparison to other polonium halides:
This potential compound is distinct from other polonium halides, such as polonium dichloride PoCl2 and polonium dibromide PoBr2 [3] With bromine vapors, polonium(II) chloride reacts to form pink polonium dichlorodibromide PoCl2Br2 [4] [5]
