The oxidation state of gold in H[AuCl4] and [AuCl4] anion is +3. The salts of H[AuCl4] (tetrachloroauric(III) acid) are tetrachloroaurates(III), containing [AuCl4] anions (tetrachloroaurate(III) anions), which have square planar molecular geometry. The Au–Cl distances are around 2.28 Å. Other d complexes adopt similar structures, e.g. tetrachloroplatinate(II) [PtCl4] . een functieprofiel
