Abstract

In the title compound, C21H18O5S2, the two sulfur-bound phenyl rings lie on opposite sides of the meth­oxy­phenyl group, making dihedral angles of 77.58 (8) and 87.45 (8)°with it. The dihedral angle between the sulfur-bound phenyl rings is 57.31 (8)°. In the crystal, π–π stacking is observed between the two sulfur-bound phenyl rings, with a centroid–centroid distance of 3.878 (1) Å and a dihedral angle of 7.58 (8)°. The mol­ecules are linked by weak C—H⋯O and C—H⋯π contacts.
