Abstract: The title compound, [Au^IIICl₂(C₁₂H₁₂N₂)]₂[Au^IIICl₄][Au^ICl₂], contains three distinct types of Au atom. In the cation, the Au^III atom is four-coordinated in a distorted square-planar arrangement by an N,N'-bidentate 5,5'-dimethyl-2,2'-bipyridine ligand and two terminal Cl atoms. In the [AuCl₄]^- anion, the centrosymmetric Au^III atom has a square-planar coordination. The centrosymmetric [AuCl₂]^- anion is linear. Intra- and intermolecular C-HCl hydrogen bonds help to establish the conformation and packing.
