Chloryl tetraperchloratoaurate is an inorganic chemical compound with the formula {{chem2|[ClO2]+[Au(ClO4)4]-}} consisting of the chloryl cation and a tetraperchloratoaurate(III) 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:{{cite journal |author1=Jean-Louis Pascal |author2=Frédéric Favier |title=Inorganic perchlorato complexes |journal=Coordination Chemistry Reviews |date=1998 |volume=178–180 |pages=865–902 |doi=10.1016/S0010-8545(98)00102-7 |language=en}}
:{{chem2|2 AuCl3 + 8 Cl2O6 → 2 [ClO2][Au(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.
