ABSTRACT
In the title hydrated mol-ecular salt, C(9)H(10)N(3)O(+)·C(7)H(7)O(3)S(-)·H(2)O, the cation is protonated at a quinazolinone N atom and an intra-molecular N-Hâ¯O hydrogen bond occurs. In the crystal structure, inter-molecular N-Hâ¯O and O-Hâ¯O hydrogen bonds and C-Hâ¯O, C-Hâ¯π and weak aromatic π-π stacking inter-actions [centroid-centroid separations = 3.8648â
(12) and 3.9306â
(13)â
Å] help to establish the packing; a short S=Oâ¯π contact is also seen.
