(Z)-3-Allyl-5-(3-methoxybenzylidene)-2-sulfanylidene-1,3-thiazolidin-4-one

In the title compound, C14H13NO2S2, the rhodanine ring and the 3-methoxybenzylidene ring are nearly coplanar, as indicated by the dihedral angle of 1.77 (6)° between their planes. The allyl group is nearly perpendicular to the rhodanine ring, with a dihedral angle of 83.64 (19)°. An intramolecular C—H...S interaction forms an S(6) ring motif. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds into inversion dimers.
