4-(4-Chloro­phen­yl)-1-[2-(2,4-dichloro­phen­oxy)propano­yl]thio­semicarbazide

The title compound, C16H14Cl3N3O2S, is an important inter­mediate for the synthesis of biologically active heterocyclic compounds. The chloro- and dichloro­phenyl rings are oriented at a dihedral angle of 40.41 (3)°. The intra­molecular N—H⋯O hydrogen bond results in the formation of a nearly planar five-membered ring, which is oriented at dihedral angles of 24.36 (3) and 22.27 (3)° with respect to the chloro- and dichloro­phenyl rings, respectively. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules.
