The title compound, C14H12INO3S, crystallizes with two independent molecules (A and B) in the asymmetric unit. The dihedral angle between the two aryl rings is 83.1 (4)° in molecule A and 79.8 (4)° in molecule B. In the crystal, the two molecules are linked by a pair of N—H...O hydrogen bonds, forming an A–B dimer with an R22(8) ring motif. The dimer is further strengthened by a pair of C—H...O hydrogen bonds with an R22(14) motif. Another pair of C—H...O interactions assembles these dimers along the diagonal of the bc plane, forming ribbons. Adjacent ribbons are connected by C—H...πaryl interactions between the A molecules, and thus the overall supramolecular architecture is one-dimensional.
