title: 1H-Pyrazolo[4,3-g]benzothia-zol-7-amine.
abstract: The mol-ecule of the title compound, C(8)H(6)N(4)S, is almost planar [maximum deviation from the mean plane = 0.020 (1) Å for the S atom]. In the crystal, a supra-molecular 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].
