6,6'-Dimethyl-2,2'-bipyridin-1-ium tetra-chloridoaurate(III).

In the anion of the title compound, (C(12)H(13)N(2))[AuCl(4)], the Au(III) atom has a square-planar coordination. In the crystal, inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds and π-π contacts between the pyridine rings [centroid-centroid distance = 3.5419 (19) Å] result in the formation of a supra-molecular structure.
