Abstract
In the crystal of the title compound, C8H8ClN3S, molecules are connected by N-H center dot center dot center dot S hydrogen bonds into strips parallel to the (112) planes and running along [1 (1) over bar0]. One of the amino H atoms is not involved in a classical hydrogen bond. In addition, there is a rather short intermolecular Cl center dot center dot center dot S distance of 3.3814 (5) angstrom.
