Deskripsi
In the title hydrated molecular salt, C9H10N3O+·C7H7O3S−·H2O, the cation is protonated at a quinazolinone N atom and an intramolecular N—H...O hydrogen bond occurs. In the crystal structure, intermolecular N—H...O and O—H...O hydrogen bonds and C—H...O, C—H...π and weak aromatic π–π stacking interactions [centroid–centroid separations = 3.8648 (12) and 3.9306 (13) Å] help to establish the packing; a short S=O...π contact is also seen.
