title: 3,3'-(1-Oxopropane-1,3-di-yl)bis-(1,3-thia-zolidine-2-thione) chloro-benzene hemisolvate.
abstract: The title compound, C9H12N2OS4·0.5C6H5Cl, which contains two 1,3-thia-zolidine-2-thione rings, is a by-product of the synthesis of 3-acryloyl-1,3-thia-zolidine-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-H⋯O interactions. The chloro-benzene solvent mol-ecule 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].
