title: N-{4-[(3,4-Dimethyl-phen-yl)sulfamo-yl]phen-yl}acetamide.
abstract: Two independent mol-ecules comprise the asymmetric unit of the title compound, C(16)H(18)N(2)O(3)S. Small but significant twists about the (S)N-C and S-C bonds differentiate the mol-ecules but the most obvious difference is found in the relative orientation of the meta-methyl groups, which lie on opposite sides of the mol-ecules. Overall, both mol-ecules adopt a U shape but with significant twisting evident, particularly in the second independent mol-ecule [dihedral angles between benzene rings = 63.90 (13) and 35.78 (11)°]. In the crystal, N-H⋯O hydrogen bonds lead to supra-molecular chains with a tubular topology propagating in [100] and C-H⋯O contacts cross-link the chains.
