N-{4-[(3-Methyl-phen-yl)sulfamo-yl]phen-yl}benzamide.

In the title compound, C(20)H(18)N(2)O(3)S, the dihedral angle between the central benzene ring and the amide group is 24.1 (3)° and that between this ring and the aromatic ring of the tolyl group is 68.2 (16)°. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a linear chain running along [100]. Weak C-H⋯O contacts also occur. Extensive weak π-π inter-actions exist from both face-to-face and face-to-edge inter-actions occur between the aromatic rings [centroid-centroid distances = 3.612 (2) and 4.843 (2) Å].
