Chloryl tetraperchloratoaurate is an inorganic chemical compound with the formula ClO₂Au(ClO₄)₄ consisting of the chloryl cation and a tetraperchloratoaurate anion. It is an orange solid that readily hydrolyzes in air.[1]

Production and reactions

Chloryl tetraperchloratoaurate is produced by the oxidation of gold metal, gold(III) chloride, or chloroauric acid by dichlorine hexoxide:[1][2]

2 AuCl₃ + 8 Cl₂O₆ → 2 ClO₂Au(ClO₄)₄ + 6 ClO₂ + 3 Cl₂

A production of gold(III) perchlorate is attempted by heating this compound, but it instead forms an oxy-perchlorato derivative.[1]
