Abstract :
In the title salt, C6H9ClN3+·C6H3O4S−, the cations and anions are linked via O—H⋯O and N—H⋯O hydrogen bonds, forming R66(37) ring motifs that are interconnected with each other, producing sheets. Separate parallel inversion-related sheets are linked through N—H⋯N and π–π stacking interactions [centroid–centroid distance = 3.5414 (13) Å], forming double layers parallel to (101). Weak C—H⋯O and C—H⋯S hydrogen bonds, as well as C—H⋯π interactions, connect the double layers into a three-dimensional network.
