2-Chloro-N-(4-meth-oxy-benzo-yl)-benzene-sulfonamide.

In the title compound, C14H12ClNO4S, the dihedral angle between the aromatic rings is 82.07 (1)° and the dihedral angle between the planes defined by the S-N-C=O fragment and the sulfonyl benzene ring is 82.46 (3)°. In the crystal, the mol-ecules are linked into C(4) chains running along [001] by strong N-H⋯O hydrogen bonds. A C-H⋯O intera-ction reinforces the [001] chains: its graph-set symbol is C(7). The chains are cross-linked into (100) sheets by further C-H⋯O inter-actions as C(6) chains along [001]. The structure also features weak π-π stacking inter-actions [centroid-centroid distances = 3.577 (1) and 3.8016 (1) Å].
