چکیده
The title Schiff base compound, C(8)H(7)ClN(4)O(2)S, was prepared by the reaction of equimolar quanti-ties of 2-chloro-5-nitro-benzaldehyde with thio-semicarbazide in methanol. The mol-ecule adopts a trans configuration with respect to the azomethine group and the dihedral angle between the benzene ring and the thio-semicarbazide group is 6.8 (3)°. In the crystal, mol-ecules are linked through inter-molecular N-H⋯S hydrogen bonds, forming chains propagating in [010].
