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.
