چکیده
In the title compound, C13H10BrNOS2, the rhodanine (systematic name: 2-sulfanyl-idene-1,3-thia-zolidin-4-one) and the 3-bromo-benzyl-idene 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-bromo-benzyl-idene 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, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(10) ring motif.
