چکیده

The title compound, C(9)H(7)Cl(2)N(3)OS, was synthesized by the reaction of 2,4-dichloro-phenoxy-acetic acid and thio-semicarbazide. The dihedral angle between the thia-diazole and benzene rings is 21.5 (2)°. In the crystal, inter-molecular N-H⋯N hydrogen bonding links the mol-ecules into chains along the b axis.

In the title compound, C(12)H(12)N(6)S(4), the two terminal thia-diazole rings are twisted with respect to the central benzene ring, making dihedral angles of 54.28 (4) and 76.56 (3)°. The dihedral angle between the two thia-diazole rings is 27.77 (4)°. Inter-molecular N-H⋯N hydrogen bonds stabilize the crystal packing, linking the mol-ecules into a tape along the b axis.
