Abstract
The structure of the title compound, C(7)H(9)NO(2)S, was previously determined from powder diffraction data [Tremayne, Seaton & Glidewell (2002). Acta Cryst. B58, 823-834]. It has now been refined to a significantly higher precision. The amino N-atom is bent with a C-C-S-N torsion angle of -65.8 (2)deg;. In the crystal, mol-ecules are packed into a three-dimensional framework/supramolecular structure through hydrogen bonds between the two H atoms of the sulfonamide group and sulfonyl O atoms of neighbouring mol-ecules.
