Abstract

All non-H atoms of the cation of the title salt, C6H5N2+·HSO4−, are essentially coplanar [r.m.s. deviation = 0.005 (1) Å] . In the crystal, N—H⋯O and O—H⋯O hydrogen bonds and weak C—H⋯O and C—H⋯N inter­actions link the mol­ecules into a two-dimensional network parallel to the (001) plane. Weak π–π stacking inter­actions between the pyridine rings of neighbouring mol­ecules further stabilize the structure [centroid–centroid distance = 3.785 (1) Å].
