Abstract
The title compound, C10H10N2 2+·C10H8O4 2−, has inversion centres located at the geometric centres of the 1,4-phenylenediacetate anion and 4,4′-bipyridinium cation. The anions and cations are connected by N—H⋯O hydrogen bonds, forming one-dimensional supramolecular chains, which interact with each other via π–π interactions [centroid–centroid distance = 3.938 (2) Å], building a two-dimensional supramolecular sheet.
