Gold(II) sulfate is the chemical compound with the formula AuSO4 or more correctly Au2(SO4)2. This compound was previously thought to be a mixed-valent compound as AuIAuIII(SO4)2. But later, it was shown that it contained the diatomic cation, Au4+ 2 which made it the first simple inorganic gold(II) compound. The bond distance between the gold atoms in the diatomic cation is 249 pm.[1][2]
Gold(II) sulfate
Structure of gold(II) sulfate(Red spheres: Au; Yellow spheres: S; Blue spheres: O)
Gold(II) sulfate is produced by reaction of sulfuric acid and gold(III) hydroxide. Gold(II) sulfate is unstable in air and oxidizes to hydrogen disulfoaurate(III)(HAu(SO4)2).[1]
