Chloryl tetraperchloratoaurate

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.

Production and reactions
Chloryl tetraperchloratoaurate is produced by the oxidation of gold metal, gold(III) chloride, or chloroauric acid by dichlorine hexoxide:
 * 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.
