Polonium tetrachloride (also known as polonium(IV) chloride) is a chemical compound with the formula Po Cl₄. The salt is a hygroscopic bright yellow crystalline solid at room temperature. Above 200 °C, it tends to decompose into polonium dichloride and excess chlorine, similar to selenium tetrachloride and tellurium tetrachloride.
