Abstract
The molecule of the title compound, C15H15NO3S, has a twisted U-shaped conformation: the twist occurs at the central C-S(=O)(2)-C-C-C unit and the benzene ring makes a dihedral angle of 28.74 (7)degrees with the phenyl ring. The S-C-C=N torsion angle is -88.95 (13)degrees. In the crystal, inversion dimers linked by pairs of O-H center dot center dot center dot N hydrogen bonds generate R-2(2)(6) loops, and C-H center dot center dot center dot O hydrogen bonds connect the dimers into a three-dimensional network.
