Abstract: In the title molecule, C7H4N2O2S2, the nitro group is twisted by 5.5 (1)° from the plane of the attached benzene ring. In the crystal, N-H...S hydrogen bonds link pairs of molecules into inversion dimers, which are linked by weak C-H...O interactions into sheets parallel to (101). The crystal packing exhibits short intermolecular S...O contacts of 3.054 (4) Å and [pi]-[pi] interactions of 3.588 (5) Å between the centroids of the five- and six-membered rings of neighbouring molecules.
