title: 4-Amino-3,5-dichloro-benzene-sulfonamide.
abstract: In the title compound, C(6)H(6)Cl(2)N(2)O(2)S, the O atoms of the sulfonamide group lie on one side of the benzene ring and the amino group lies on the opposite side. An inter-molecular N-H⋯Cl inter-action occurs. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a three-dimensional structure with supporting π-π stacking inter-actions [centroid-centroid distance = 3.7903 (12) Å]. A short Cl⋯Cl contact [3.3177 (10) Å] also occurs.
