Abstract:
In the title compound, C(21)H(18)O(5)S(2), the two sulfur-bound phenyl rings lie on opposite sides of the meth-oxy-phenyl 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 mol-ecules are linked by weak C-H⋯O and C-H⋯π contacts.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
