Crystal structure of (Z)-3-allyl-5-(3-bromobenzylidene)-2-sulfanylidene-1,3-thiazolidin-4-one

Abstract

In the title compound, C13H10BrNOS2, the rhodanine (systematic name: 2-sulfanylidene-1,3-thiazolidin-4-one) and the 3-bromobenzylidene ring systems are inclined slightly, forming a dihedral angle of 5.86(12)°. The rhodanine moiety is linked to an allyl group at the N atom and to the 3-bromobenzylidene ring system. The allyl group, C=C - C, is nearly perpendicular to the mean plane through the rhodanine ring, maling a dihedral angle of 87.2(5)°. In the crystal, molecules are linked by pairs of C - H⋯O hydrogen bonds, forming inversion dimers with an R 2 2(10) ring motif.
