Abstract: The title molecule, C19H12S2O2, lies on a twofold rotation axis. The thiochromonone unit is essentially planar, with a maximum deviation of 0.0491 (14) Å. The dihedral angle between the thiochromenone ring systems is 64.48 (4)°. In the crystal, there are weak [pi]-[pi] stacking interactions, with a centroid-centroid distance of 3.7147 (9) Å.
