2-(4-Sulfamoylphenyl)hydrazin-1-ium chloride

The hydrazinium residue in the cation of the title salt, C(6)H(10)N(3)O(2)S(+)·Cl(-), is twisted out of the plane of the benzene ring to which it is attached [N-N-C-C torsion angle = 25.9 (2)°] and the amino group is almost perpendicular to the benzene ring [N-S-C-C torsion angle = 88.71 (16)°]. In the crystal, the cations are linked by N-H⋯O hydrogen bonds and π-π inter-actions [ring centroid distance = 3.7280 (11) Å], forming layers in the bc plane that are connected by N-H⋯Cl hydrogen bonds.
