N-{4-[(4-Methyl-phen-yl)sulfamo-yl]phen-yl}acetamide

Abstract

The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38 (14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03 (10)°. The crystal packing features N-H⋯O hydrogen bonding, which leads to supra-molecular chains with a tubular topology along the b axis. Intra-molecular C-H⋯O inter-actions are also observed.
