The title compound, C 13 H 10 N + ·C 7 H 4 NO 4− ·H 2 O or (acrH) + (pydcH) − ·H 2 O, is a monohydrate of acridinium cations and a mono-deprotonated pyridine-2,6-dicarb­oxy­lic acid. The structure contains a range of non-covalent inter­actions, such as O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds, as well as π–π stacking [range of centroid–centroid distances = 3.4783 (5)–3.8059 (5) Å]. The N—H⋯O hydrogen bond between the donor acridinium cation and the carboxyl­ate acceptor is particularly strong. The average separation between the π-stacked acridinium planes is 3.42 (3) Å.
