organic compounds
In the crystal structure of the title compound, C13H11NO5S, the dihedral angle between the mean planes of the 4-tolyl and 2-nitrophenyl rings is 42.2 (2)°. There are weak C—HO hydrogen bonds, which generate rings of graph-set motifs S(5), (4), (5), (6), (6), (7) and (10). The supramolecular aggregation is completed by the presence of intermolecular van der Waals short contacts, and C—Hπ and π–π interactions.
