2 + 2 → 2 + 2 → + 2

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

Chlorine perchlorate

Chlorine perchlorate is the chemical compound with the formula Cl2O4. This chlorine oxide is an asymmetric oxide, with one chlorine atom in oxidation state +1 and the other +7, with proper formula ClOClO3...

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 gold

Gold

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...

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
