6,6′-Dimethyl-2,2′-bipyridin-1-ium tetrachloridoaurate(III)

In the anion of the title compound, (C12H13N2)[AuCl4], the AuIII atom has a square-planar coordination. In the crystal, intermolecular 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 supramolecular structure
