2-Chloro-N-(3-meth-oxy-benzo-yl)benzene-sulfonamide.

In the title compound, C14H12ClNO4S, the dihedral angle between the chloro- and meth-oxy-substituted benzene rings is 87.40 (1)°. In the crystal, adjacent mol-ecules form inversion-related dimers through strong N-H⋯O hydrogen bonds, generating R 2 (2)(8) loops. The dimers are further connected through two C-H⋯O inter-actions that form C(11) chains and R 2 (2)(14) loops. Aromatic π-π stacking inter-actions [centroid-centroid separation = 3.8574 (1) Å] are also observed.

N-[(2-Chloro-phen-yl)sulfon-yl]-3-nitro-benzamide.

In the title compound, C13H9ClN2O5S, the dihedral angle between the benzene rings is 74.86 (11)°. The mol-ecule is twisted at the S atom, with a dihedral angle of 82.53 (13)° between the sulfonyl benzene ring and the S-N-C=O segment. In the crystal, mol-ecules are linked into inversion dimers through pairs of N-H⋯O hydrogen bonds, thereby forming R 2 (2)(8) loops. Mol-ecules are linked into C(7) [010] chains by weak C-H⋯O hydrogen bonds, and C-H⋯π inter-actions are also observed.
