O, the coordination around the S atom is distorted tetrahedral. The aromatic rings are oriented at a dihedral angle of 74.18 (17)°. Intramolecular C—H⋯O 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—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds link the molecules. π–π Contacts between the phenyl rings [centroid–centroid distance = 3.726 (3) Å] may further stabilize the structure. There is also a C—H⋯π interaction.
