In the title compound, C14H13ClN4S, obtained from a reaction of 2-benzoyl-4-chloro-aniline with thio-semicarbazide in ethanol, the dihedral angle between the aromatic rings is 81.31 (13)°. In the crystal, the mol-ecules are linked by three N-H⋯S hydrogen bonds, forming centrosymmetric rings with set-graph motif R 2 (2)(8) and R 2 (2)(18), and resulting in the formation of a two-dimensional network lying parallel to (010).
