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

Abstract

In the title hydrated salt, C 6H 9N 2O +·C 14H 9O 3 -·H 2O, the dihedral angle between the benzene rings of the 2-benzoyl-benzoate 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 R 2 2(8), R 6 6(16) and R 4 4(6) motifs. The crystal packing is further stabilized by two ?-? 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.
