In the title compound, C8H5NOS2, the non-H atoms are approximately coplanar [maxium deviation = 0.060 (3) Å]. The dihedral angle between the least-squares planes of the pyridine and 1,3-dithiol-2-one rings is 5.96 (17)°. The crystal packing is stabilized by weak intermolecular C—H⋯O hydrogen bonds and by an S⋯S close contact [3.510 (5) Å].

The title compound was synthesized according to a literature procedure (Han et al., 2007). Slow evaporation of a solution in THF gave single crystals suitable for X-ray analysis.
All H atoms were placed geometrically (C—H = 0.94 Å) with Uiso = 1.2Ueq of the parent atom.

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. |

Bifunctional molecules featuring a TTF (tetrathiafulvalene) unit with a pyridine, TTF-py, have been explored and a series of new TTF compounds with transition metal centers have been synthesized. The title compound is an intermediate for synthesis of this type of TTF derivative and also a donor-acceptor ligand.
In the title compound (Fig. 1), all bonds lengths and angles are found to be within the range for 4-pyridine-4-yl-1,3-dithiol-2-one (Han et al., 2007). In addition, the non-H atoms are approximately planar [maxium deviation = 0.060 (3) Å] (Fig. 1). There are short S···S contacts [3.510 (5) Å] and weak C—H···O intermolecular hydrogen bonds in the crystal structure (Table 1, Fig.2).
