Abstract
In the title compound, C10H9ClN4OS, an intramolecular N-H center dot center dot center dot O hydrogen-bonding interaction and an N-H center dot center dot center dot N interaction generate ring motifs [graph sets S(6) and S(5), respectively]. In the crystal, molecules form a chain through N-H center dot center dot center dot O hydrogen bonds, and these are extended by N-H center dot center dot center dot S hydrogen-bonding interactions into an infinite three-dimensional network. The crystal structure also exhibits weak C-H center dot center dot center dot pi interactions.
