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

[edit]

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]
