%X The title compound, C13H10N+¡¤C7H4NO4 ¡¤H2O or (acrH)+(pydcH) ¡¤H2O, 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¡ªH...O, O¡ªH...N and N¡ªH...O hydrogen bonds, as well as ¦Ð¨C¦Ð stacking [range of centroid¨Ccentroid distances = 3.4783 (5)¨C3.8059 (5)  ]. The N¡ªH...O hydrogen bond between the donor acridinium cation and the carboxylate acceptor is particularly strong. The average separation between the ¦Ð-stacked acridinium planes is 3.42 (3)  .
