Abstract: In the molecule of the title compound, C₁₃H₁₀INO₄S·H₂O, the coordination around the S atom is distorted tetrahedral. The aromatic rings are oriented at a dihedral angle of 74.18 (17)°. Intramolecular C-HO hydrogen bonds result in the formation of non-planar five- and six-membered rings, which adopt envelope and twist conformations, respectively. In the crystal structure, intermolecular N-HO, O-HO and C-HO hydrogen bonds link the molecules. - Contacts between the phenyl rings [centroid-centroid distance = 3.726 (3) Å] may further stabilize the structure. There is also a C-H interaction.
