The hydrazinium residue in the cation of the title salt, C6H10N3O2S+·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 interactions [ring centroid distance = 3.7280 (11) Å], forming layers in the bc plane that are connected by N—H⋯Cl hydrogen bonds.

Diazotization of sulfonamide with NaNO2/HCl followed by reduction with sodium sulfite afforded the title salt which was crystallized from ethanol as irregular light-brown chunks. Yield: 72%. M.pt. 488–490 K.
Carbon-bound H-atoms were placed in calculated positions [C—H = 0.95 Å, Uiso(H) = 1.2Ueq(C)] and were included in the
in the riding model approximation. The N—H atoms were located in a difference Fourier map, and were refined with a distance restraint of N—H = 0.88±0.01 Å; their Uiso values were refined.Sulphonamides related to the title salt, 2-(4-sulfamoylphenyl)hydrazinium chloride (I), are known to possess pharmacological properties. For example, N-substituted pyrazolyl-benzensulfonamides are known to selectively inhibit COX–2 (Croitoru et al., 2004) and other derivatives were reported to exhibit anti-microbial and anti-fungal activities (Dogruer et al. 2010). The crystal and molecular structure of 2-(4-sulfamoylphenyl)hydrazinium chloride (I) is reported herein, as a continuation of structural studies of these systems (Asiri et al., 2011; Asiri et al., 2012).
The crystallographic
of (I) comprises a hydrazinium cation charge balanced by a chloride, Fig. 1. The hydrazinium residue is twisted out of the plane of the benzene ring to which it is attached as seen in the value of the N1—N2—C4—C3 torsion angle of 25.9 (2)°. The amino group occupies a position perpendicular to the benzene ring with the N3—S1—C1—C2 torsion angle being 88.71 (16)°; the ammonium and amino groups are orientated to opposite sides of the benzene ring.The cations are linked by N—H···O hydrogen bonds, Table 1, and π—π interactions [ring centroid distance = 3.7280 (11) Å for 1 - x, 1 - y, 1 - z] to form layers in the bc plane. The cations are connected to the chloride anions by N—H···Cl hydrogen bonds, Table 1, leading to a three-dimensional architecture.

Sulphonamides related to the title salt, 2-(4-sulfamoylphenyl)hydrazinium chloride (I), are known to possess pharmacological properties. For example, N-substituted pyrazolyl-benzensulfonamides are known to selectively inhibit COX–2 (Croitoru et al., 2004) and other derivatives were reported to exhibit anti-microbial and anti-fungal activities (Dogruer et al. 2010). The crystal and molecular structure of 2-(4-sulfamoylphenyl)hydrazinium chloride (I) is reported herein, as a continuation of structural studies of these systems (Asiri et al., 2011; Asiri et al., 2012).
The crystallographic asymmetric unit of (I) comprises a hydrazinium cation charge balanced by a chloride, Fig. 1. The hydrazinium residue is twisted out of the plane of the benzene ring to which it is attached as seen in the value of the N1—N2—C4—C3 torsion angle of 25.9 (2)°. The amino group occupies a position perpendicular to the benzene ring with the N3—S1—C1—C2 torsion angle being 88.71 (16)°; the ammonium and amino groups are orientated to opposite sides of the benzene ring.
The cations are linked by N—H···O hydrogen bonds, Table 1, and π—π interactions [ring centroid distance = 3.7280 (11) Å for symmetry operation: 1 - x, 1 - y, 1 - z] to form layers in the bc plane. The cations are connected to the chloride anions by N—H···Cl hydrogen bonds, Table 1, leading to a three-dimensional architecture.
