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—H⋯O 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].

The procedure for the synthesis of 3-acryloyl-1,3-thiazolidine-2-thione was modeled after that of Evans & Thomson (2005). Briefly, 1,3-thiazolidine-2-thione (2.27 g, 19.0 mmol) and Et3N (1.93 g, 18.9 mmol) in CH2Cl2 (50 ml) were added to a round-bottom flask with an egg-shaped stir bar and a pinch of phenothiazine inhibitor. The flask was placed in an EtOH/dry ice bath (-78°C) and kept under N2. Acryloyl chloride (1.71 g, 18.9 mmol) in CH2Cl2 (10 mL) was added dropwise to the flask over 5 minutes. The reaction mixture was slowly warmed to room temperature and stirred for 1 h. The yellow product mixture was then washed with H2O, and the aqueous layer was extracted twice with CH2Cl2. The combined organic layers were extracted twice with saturated NaHCO3, once more with H2O, dried (MgSO4), filtered, and concentrated. One grain of CuCl2 was added to the flask as polymerization inhibitor. The reaction mixture was poured into CHCl3, and the title compound precipitated as a light-yellow solid. The solid title compound was recrystallized from chlorobenzene solution to give almost colorless prisms.

H atoms were placed in calculated positions with C—H = 0.99 Å for the CH2 H atoms, and refined using riding model, with Uiso(H) = 1.2Ueq(C,N). There was a molecule of chlorobenzene located on an inversion center but disordered over multiple conformations. After unsuccessful attempts to model this SQUEEZE was used to remove its contribution (Van der Sluis & Spek, 1990).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, 3,3'-(1-oxopropane-1,3-diyl)bis(1,3-thiazolidine-2-thione), is a by-product of the synthesis of 3-acryloyl-1,3-thiazolidine-2-thione. The formation of the title compound results from a nucleophilic attack of the nitrogen of excess 1,3-thiazolidine-2-thione, on the terminal alkene of 3-acryloyl-1,3-thiazolidine-2-thione.
The crystallographic data show both of the thiazolidine-2-thione rings display a twist conformation; C2 and C3 are displaced 0.269 (4) Å and -0.070 (4) Å respectively from the mean N1 C1 S1 S2 plane, while C8 and C9 are displaced 0.118 (4) Å and -0.175 (4) Å respectively from the mean N2 C7 S3 S4 plane. These two planes form a dihedral angle of 79.97 (9)°. The amide present in the title compound is nearly flat, with a twist angle about the C4–N1 bond of 5.6 (1)° (calculated according to the definition given by Yamada 1993).
Figure 2 shows the molecular packing for C9H12N2OS4, modified using the SQUEEZE function. The void in the center of the unit cell contains a disordered molecule of chlorobenzene, the recrystallization solvent used in this experiment, lying on a center of inversion.
