N-(3-Chloro­phen­yl)-1,2-benzisothia­zol-3-amine 1,1-dioxide

In the title compound, C13H9ClN2O2S, the dihedral angle between the aromatic ring systems is 6.00 (12)° and an intra­molecular C—H⋯N inter­action generates an S(6) ring. In the crystal, mol­ecules inter­act by way of C—H⋯O and N—H⋯O bonds, generating R21(7) and R22(10) ring motifs, and aromatic π–π stacking inter­actions [centroid–centroid separations = 3.730 (3) and 3.733 (2) A] help to consolidate the packing.
