The structures of the AuCl<SUB>4</SUB><SUP>−</SUP> and the AuBr<SUB>4</SUB><SUP>−</SUP> complexes in aqueous solutions have been determined from X-ray scattering measurements on concentrated solutions of tetrachloroauric and tetrabromoauric acids. Both the tetrachloroaurate(III) and the tetrabromoaurate(III) complexes were found to have a square planar symmetry. The values obtained for the interatomic distances within the complexes are: Au–Cl, 2.29<SUB>1</SUB> Å; <I>cis</I>-Cl–Cl, 3.24 Å; <I>trans</I>-Cl–Cl, 4.58 Å; Au–Br, 2.43<SUB>2</SUB> Å; <I>cis</I>-Br–Br, 3.44 Å; <I>trans</I>-Br–Br, 4.86 Å.
