Abstract
The title mol-ecule, C19H12S2O2, lies on a twofold rotation axis. The thio-chromonone unit is essentially planar, with a maximum deviation of 0.0491 (14) Å. The dihedral angle between the thio-chromenone ring systems is 64.48 (4)°. In the crystal, there are weak π-π stacking inter-actions, with a centroid-centroid distance of 3.7147 (9) Å.
