(E)-Methyl 3-(2-nitrobenzylidene)dithiocarbazate

Abstract

The asymmetric unit of the title compound, C9H9N3O2S2, contains two independent molecules, A and B, with similar bond dimensions. In both molecules, the nitro group is tilted with respect to the aromatic ring [dihedral angles 32.0 (1)° in molecule A and 34.0 (1)° in molecule B]. The dithiocarbazate unit is nearly coplanar with the aromatic ring in both molecules. For molecule B, pairs of molecules are linked by N—H...O and C—H...O hydrogen bonds about a centre of symmetry to form a dimer, whereas molecules A are not involved in hydrogen bonding in the crystal structure.
