The molecule of the title compound, C8H6N4S, is almost planar [maximum deviation from the mean plane = 0.020 (1) Å for the S atom]. In the crystal, a supramolecular three-dimensional arrangement arises from N—H⋯N hydrogen bonds and weak aromatic stacking interactions along the a axis [centroid–centroid separation = 3.582 (2) Å].
