Bromine dioxide is the chemical compound composed of bromine and oxygen with the formula BrO2. It forms unstable yellow[2] to yellow-orange[1] crystals. It was first isolated by R. Schwarz and M. Schmeißer in 1937 and is hypothesized to be important in the atmospheric reaction of bromine with ozone.[3] It is similar to chlorine dioxide, the dioxide of its halogen neighbor one period higher on the periodic table.[citation needed]
Reactions
Bromine dioxide is formed when an electric current is passed through a mixture of bromine and oxygen gases at low temperature and pressure.[4]
Bromine dioxide can also be formed by the treatment of bromine gas with ozone in trichlorofluoromethane at −50 °C.[1]
