:
It is a dark red fuming liquid at room temperature that crystallizes as an ionic compound, chloryl perchlorate, . It was originally reported to exist as the monomeric chlorine trioxide ClO3 in gas phase, but was later shown to remain an oxygen-bridged dimer after evaporation and until thermal decomposition into chlorine perchlorate
, Cl2O4, and oxygen.

and perchloric acid
Perchloric acid
Perchloric acid is the inorganic compound with the formula HClO4. Usually encountered as an aqueous solution, this colourless compound is a strong acid comparable in strength to sulfuric and nitric acids. It is a powerful oxidizer, but its aqueous solutions up to appr. 70% are remarkably inert,...
s. It is produced by reaction between chlorine dioxide
Chlorine dioxide
Chlorine dioxide is a chemical compound with the formula ClO2. This yellowish-green gas crystallizes as bright orange crystals at −59 °C. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleaching....

Properties
Cl2O6 is diamagnetic and is a very strong oxidizing agent. Although stable at room temperature, it explodes violently on contact with organic compounds and reacts with goldGold
Gold is a chemical element with the symbol Au and an atomic number of 79. Gold is a dense, soft, shiny, malleable and ductile metal. Pure gold has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. Chemically, gold is a...

In chemistry, chloryl refers to the red-colored cation having the chemical formula . It is polyatomic ion, structurally identical to chlorite and having the same chemical formula but with chlorine in the +5 oxidation state rather than +3...
salt . Many other reactions involving Cl2O6 reflect its ionic structure, , including the following:
- NO2F + Cl2O6 → NO2ClO4 + ClO2F
- NO + Cl2O6 → NOClO4 + ClO2
- 2 V2O5 + 12 Cl2O6 → 4 VO(ClO4)3 + 12 ClO2 + 3 O2
- SnCl4 + 6 Cl2O6 → [ClO2]2[Sn(ClO4)6] + 4 ClO2 + 2 Cl2
Nevertheless, it can also react as a source of the ClO3 radical:
- 2 AsF5 + Cl2O6 → 2 ClO3AsF5
