2-Amino-3-(hydroxymethyl)pyridinium 2-benzoylbenzoate monohydrate

In the title hydrated salt, C6H9N2O+·C14H9O3−·H2O, the dihedral angle between the benzene rings of the 2-benzoylbenzoate anion is 82.04 (14)°, while the angles between the aromatic ring of the pyridinium cation and each of the benzene rings of the anion are 4.42 (14) and 82.04 (14)°. In the crystal, molecules are linked by N—H...O and O—H...O hydrogen bonds, generating a three-dimensional network with R22(8), R66(16) and R44(6) motifs. The crystal packing is further stabilized by two π–π interactions, one between pyridinium rings, and another between the benzene benzoate and pyridinium rings of neighbouring molecules, with centroid-to-centroid distances of 3.559 (2) and 3.606 (2) Å, respectively.
