Tetrabromoauric acid is an inorganic compound with the formula H[AuBr4]. It is the bromide analog of chloroauric acid. It is generated analogously, by reacting a mixture of hydrobromic and nitric acids with elemental gold.[1][2] The oxidation state of gold in H[AuBr4] and [AuBr4] anion is +3. The salts of H[AuBr4] (tetrabromoauric(III) acid) are tetrabromoaurates(III), containing [AuBr4] anions (tetrabromoaurate(III) anions), which have square planar molecular geometry.
