N-(4-Chlorophenylsulfonyl)-4-iodobenzamide

Abstract

In the title compound, C13H9ClINO3S, the benzene rings are inclined to one another by 81.6 (2)°. In the crystal, molecules are linked by pairs of N—H...O hydrogen bonds, forming inversion dimers with an R 2 2(8) ring motif. The dimers are linked by C—H...O hydrogen bonds, forming sheets parallel to the bc plane. Neighbouring sheets are linked via offset π–π interactions involving inversion-related iodobenzene rings [intercentroid distance = 3.807 (3) Å], forming a three-dimensional supramolecular structure.
