Polonium dichloride dibromide – Wikipedia

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.

Is a hypothetical or unstable mixed-halide compound with the formula ${\displaystyle PoCl2Br2}$. It is thought to form from the reaction of polonium dichloride ${\displaystyle PoCl2}$ with bromine vapor, producing a salmon-pink solid. Because polonium is highly radioactive, such compounds have no practical applications outside research.

Formation: Reacting polonium dichloride PoCl2 with bromine vapor forms a salmon-pink product.

Formula: ${\displaystyle PoCl2Br2}$

Stability: Unstable mixed halide compound.

Color: Salmon-pink solid.

Analysis: X-ray powder photography indicates the absence of ${\displaystyle PoCl2}$, ${\displaystyle PoCl4}$, and ${\displaystyle PoBr4}$, but data are insufficient to determine a full structure.

Polonium dibromide ${\displaystyle PoBr2}$: Purple-brown crystalline solid; sublimes at 110 °C and decomposes when melted at 270–280 °C.

Polonium dichloride ${\displaystyle PoCl2}$: Ionic polonium–chlorine compound.

Polonium tetrachloride ${\displaystyle PoCl4}$: Another known polonium halide.

Radioactivity: Polonium is extremely radioactive and toxic

Usage: No practical uses outside scientific research due to extreme danger.
