Abstract

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].
