The title compound, C11H8ClN3OS, was prepared by the reaction of N-cyanoiminothiazolidine, 2-aminoethanethiol and triethylamine at 350 K. The dihedral angle between the two rings is 62.5 (8)°.

A mixture of N-cyanoiminothiazolidine 10 mmol (1.27 g), 2-amino-ethanethiol (1.75 g, 10 mmol) and (1.01 g, 10 mmol) triethylamine was refluxed in absolute acetone (25 ml) for 4 h. On cooling, the product crystallized, was filtered, and recrystallized from absolute EtOH (yield 2.42 g (91%)). Single crystals suitable for X-ray measurements were obtained by recrystallization from ethanol at room temperature.
H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H distances of 0.93–0.97 Å, respectively, and Uiso(H) = 1.2 Ueq of the parent atoms.

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. |

Thiazolidine is an important group in organic chemistry. Many compounds containing thiazolidine groups possess a broad spectrum of biological activities (Iwata et al., 1988; Huang & Shi, 1990).
In the crystal structure (Fig. 1), the torsion angle formed by atoms N1, C8, C9 and S1 was 34.5 (9)°. The dihedral angle formed by the the ring (N1, C8, C9, C10 and S1) and the phenyl ring (C1-C6) was 62.5 (8)°. The C=N bond length (1.299 (2) Å) is in agreement with that observed before (Jian et al., 2006). The C—S bond length (1.734 (7) and 1.808 (2) Å) are in agreement with those observed before (Schroth et al., 1997). Intermolecular C–H···N interactions help to stabilize the crystal structure.
