4-Iodo-N-(o-tolylsulfonyl)benzamide

Abstract

The title compound, C14H12INO3S, crystallizes with two independent molecules (AandB) in the asymmetric unit. The dihedral angle between the two aryl rings is 83.1 (4)° in moleculeAand 79.8 (4)° in moleculeB. In the crystal, the two molecules are linked by a pair of N—H...O hydrogen bonds, forming anA–Bdimer with anR22(8) ring motif. The dimer is further strengthened by a pair of C—H...O hydrogen bonds with anR22(14) motif. Another pair of C—H...O interactions assembles these dimers along the diagonal of thebcplane, forming ribbons. Adjacent ribbons are connected by C—H...πarylinteractions between theAmolecules, and thus the overall supramolecular architecture is one-dimensional.
