Cl2O6

Chlorine hexoxide, also known as dichlorine hexoxide, is a chemical compound with the formula Cl2O6. It is an unstable and highly reactive substance. At room temperature, it exists as a yellow liquid. It is a powerful oxidizing agent. The compound can be synthesized by reacting chlorine dioxide with ozone under specific conditions. Its structure is often described as a chlorine(V) cation ([ClO2]+) and a chlorine(VII) anion ([ClO4]-) dimer, though it can also exist as a radical. Exposure to heat or shock can cause it to decompose explosively, releasing oxygen and chlorine. Due to its instability and reactivity, Cl2O6 is not commonly encountered outside of specialized research laboratories. Its handling requires extreme caution and appropriate safety measures. The compound has been studied for its potential in various chemical reactions, particularly those involving oxidation. Its decomposition products are primarily oxygen and chlorine, which are common atmospheric gases.
