The 8H8N2O4S2, contains one half of a centrosymmetric molecule. A short C⋯O distance of 3.012 (4) Å between the carbonyl groups of neighbouring molecules indicates the presence of dipole–dipole interactions. The crystal packing exhibits also weak intermolecular O⋯S [3.239 (3) Å] and C—H⋯O interactions.

The title compound was prepared according to the method of Doğan et al. (1992). Colourless block-shape crystal of (I) suitable for X-ray diffraction was obtained from ethanol/water (V: V = 4: 1).
H atoms were found in difference map, placed in idealized positions (C—H 0.97 Å) and refined as riding, with Uiso(H) = 1.2 Ueq(C).

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 research on N-substitution 2-thioxooxazolidin-4-one compounds have been mushroomed for their interesting biological and spectral properties (Cutshall et al., 2005; Gupta et al., 1981).
The title compound is composed of two functional groups of 2-thioxooxazolidin-4-one which are bridged by ethane group (Fig.1). In the crystal, C1—C4, O1—O2, N1 and S1 atoms are almost coplanar with a highest deviation of 0.0440 Å for O2. As a derivative of ethane, the molecule has a perfect anti-linear conformation. Dihedral angle of N1—C1—C1A—N1A is -180.00 (19)°. The crystal packing exhibits weak intermolecular C—H···O hydrogen bonds (Table 1), O···S interaction (S1···O2iii 3.239 (3) Å [symmetry code: (iii) -1 + x, y, -1 + z]), and strong dipole-dipole interactions proved by short C···O distance of 3.012 (4) Å between the carbonyl groups of neighbouring molecules.
