title: N-(3-Chloro-phen-yl)-1,2-benzisothia-zol-3-amine 1,1-dioxide.
abstract: In the title compound, C(13)H(9)ClN(2)O(2)S, the dihedral angle between the aromatic ring systems is 6.00 (12)° and an intra-molecular C-H⋯N inter-action generates an S(6) ring. In the crystal, mol-ecules inter-act by way of C-H⋯O and N-H⋯O bonds, generating R(2) (1)(7) and R(2) (2)(10) ring motifs, and aromatic π-π stacking inter-actions [centroid-centroid separations = 3.730 (3) and 3.733 (2) Å] help to consolidate the packing.
