(E)-Methyl 3-(2-nitrobenzylidene)dithio-carbazate

Abstract

The asymmetric unit of the title compound, C9H9N3O2S2, contains two independent mol-ecules, A and B, with similar bond dimensions. In both mol-ecules, the nitro group is tilted with respect to the aromatic ring [dihedral angles 32.0 (1)° in mol-ecule A and 34.0 (1)° in mol-ecule B]. The dithio-carbazate unit is nearly coplanar with the aromatic ring in both mol-ecules. For mol-ecule B, pairs of mol-ecules are linked by N - H⋯O and C - H⋯O hydrogen bonds about a centre of symmetry to form a dimer, whereas mol-ecules A are not involved in hydrogen bonding in the crystal structure. © International Union of Crystallography 2008.
