The title compound, C12H9N3, is an unhydrated analogue of the previously reported trihydrate. The molecule is essentially planar, with a 3.62 (11)° angle between the pyridine and benzimidazole planes. In the crystal, N—H
N hydrogen bonds result in chains of molecules parallel to [010], which are additionally linked by weak π–π stacking interactions [centroid–centroid distance = 3.7469 (17) Å], resulting in extended sheets of molecules parallel to (103).

The asymmetric unit of the title compound, C10H8N2S2, is composed of two independent half-molecules, each residing on a center of symmetry. In the crystal, weak C—Hπ interactions join the two symmetry-independent molecules together into interlinked chains parallel to [011]. The crystal structure was refined as a two-component pseudo-merohedral twin using the twin law 001 0-10 100. The refined domain fractions are 0.516 (3) and 0.484 (3).
