The asymmetric unit of the title salt, C12H24N+·C7H3N2O6−, contains two cations and two anions. In the crystal, the cations and anions are connected by N—H⋯O hydrogen bonds, forming a 12-membered ring with an R44(12) graph-set motif. The center of this 12-membered ring coincides with an inversion centre. π–π stacking is observed between parallel benzene rings [centroid–centriod distance = 3.771 (2) Å].
