The mol-ecule of the title compound, C(14)H(12)ClN(3)OS, consists of three approximately planar fragments: the central thio-urea group, the chloro-phenyl group and the picolyl (3-methyl-pyridin-2-yl) group with a maximum of 0.035 (2)° for an N atom from the mean square plane of the central thiourea group. The central fragment forms dihedral angles of 33.30 (8) and 76.78 (8)° with the chloro-phenyl and picolyl groups, respectively. With respect to the thio-urea C-N bonds, the 4-chloro-benzoyl group is positioned trans to the thiono S atoms, whereas the picolyl group lies in a cis position to it. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by inter-molecular C-H⋯N hydrogen bonds, forming chains along the a axis.
