Polonium Halides
Polonium forms several halide compounds, some unstable or hypothetical. Due to the extreme radioactivity of polonium, all compounds are highly toxic and studied only in research.
Polonium dichloride dibromide
[edit]
Is a hypothetical or unstable mixed-halide compound with the formula P o C l 2 B r 2 {\displaystyle PoCl2Br2} . It is thought to form from the reaction of polonium dichloride P o C l 2 {\displaystyle PoCl2} with bromine vapor, producing a salmon-pink solid. Because polonium is highly radioactive, such compounds have no practical applications outside research.
Formation and properties
[edit]
Formation: Reacting polonium dichloride PoCl2 with bromine vapor forms a salmon-pink product.
Formula: P o C l 2 B r 2 {\displaystyle PoCl2Br2}
Stability: Unstable mixed halide compound.
Color: Salmon-pink solid.
Analysis: X-ray powder photography indicates the absence of P o C l 2 {\displaystyle PoCl2} , P o C l 4 {\displaystyle PoCl4} , and P o B r 4 {\displaystyle PoBr4} , but data are insufficient to determine a full structure.
Other polonium halides
[edit]
Polonium dibromide P o B r 2 {\displaystyle PoBr2} : Purple-brown crystalline solid; sublimes at 110 °C and decomposes when melted at 270–280 °C.
Polonium dichloride P o C l 2 {\displaystyle PoCl2} : Ionic polonium–chlorine compound.
Polonium tetrachloride P o C l 4 {\displaystyle PoCl4} : Another known polonium halide.
Radioactivity: Polonium is extremely radioactive and toxic
Usage: No practical uses outside scientific research due to extreme danger.
