N-{4-[(3,4-Dimethyl­phen­yl)sulfamo­yl]phen­yl}acetamide

Two independent mol­ecules 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 mol­ecules but the most obvious difference is found in the relative orientation of the meta-methyl groups, which lie on opposite sides of the mol­ecules. Overall, both mol­ecules adopt a U shape but with significant twisting evident, particularly in the second independent mol­ecule [dihedral angles between benzene rings = 63.90 (13) and 35.78 (11)°]. In the crystal, N—H⋯O hydrogen bonds lead to supra­molecular chains with a tubular topology propagating in [100] and C—H⋯O contacts cross-link the chains.
