|Section2= |Section3= }} Dichlorine hexoxide is the chemical compound with the molecular formula , which is correct for its gaseous state. However, in liquid or solid form, this chlorine oxide ionizes into the dark red ionic compound chloryl perchlorate , which may be thought of as the mixed anhydride of chloric and perchloric acids. It is produced by reaction between chlorine dioxide and excess ozone: :2 + 2 → 2 + 2 → + 2 ==Molecular structure== 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. The compound ClO3 was then rediscovered. It is a dark red fuming liquid at room temperature that crystallizes as a red ionic compound, chloryl perchlorate, . The red color shows the presence of chloryl ions. Thus, chlorine's formal oxidation state in this compound remains a mixture of chlorine (V) and chlorine (VII) both in the gas phase and when condensed; however by breaking one oxygen-chlorine bond some electron density does shifts towards the chlorine (VII). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「dichlorine hexoxide」の詳細全文を読む スポンサード リンク
