| Abstract | The whole molecule of the title compound, C23H14O6S, is disordered over two sets of sites with refined occupancies of 0.8733 (12):0.1267 (12). The dihedral angle between the mean planes through the chromene ring systems is 56.31 (5) and 55.2 (3)° for the major and minor components, respectively. In both components, a pair of intramolecular O—H⋯O interactions generate rings of S(8) graph-set motif. In the crystal, the molecules are linked by intermolecular C—H⋯O interactions, forming chains along the b axis. The structure is further stabilized by π–π interactions with centroid–centroid distances of 3.594 (2) and 3.608 (5) Å. |
