In the title molecule, C17H15ClN4S, the benzene rings form dihedral angles of 16.6 (1) and 77.2 (1)° with the triazole ring. The dihedral angle between the benzene rings is 86.6 (1)°. In the crystal, pairs of N—HS hydrogen bonds form inversion dimers with graph-set notation R22(8). Weak C—HS hydrogen bonds link these dimers into layers parallel to (100). Weak intramolecular C—HS and C—HN contacts are observed.
