3,3'-(1-Oxopropane-1,3-diyl)bis(1,3-thiazolidine-2-thione) chlorobenzene hemisolvate

Abstract: The title compound, C₉H₁₂N₂OS₄·0.5C₆H₅Cl, which contains two 1,3-thiazolidine-2-thione rings, is a by-product of the synthesis of 3-acryloyl-1,3-thiazolidine-2-thione. The dihedral angle between these rings is 79.95 (9)°, with both rings displaying a twisted conformation. The twist angle of the amide group is 5.6 (1)°. In the crystal, the molecules are linked into [001] chains by C-HO interactions. The chlorobenzene solvent molecule was found to show unresolvable disorder about a centre of inversion and its contribution to the scattering was removed with the SQUEEZE option in PLATON [Spek (2009). Acta Cryst. D65, 148-155].
