In the title compound, C11H11NO3S2, the S-Csp (2) bonds are shorter [1.746 (3) and 1.750 (2) Å] than the S-CH3 bonds [1.794 (3) and 1.806 (3) Å], which we attribute to d-π inter-actions between the S atoms and the C=C bond. The 1,1-bis-(methyl-sulfan-yl)-3-oxo-propyl-ene fragment and the 4-nitro-phenyl group are both almost planar, with the largest deviations from their mean planes being 0.053 ...

The title compound, C17H15N5O4, was obtained via the condensation of 3-eth-oxy-2-[2-(4-nitro-phen-yl)hydrazono]-3-oxo-propanoic acid with 1,2-di-amino-benzene. In the mol-ecule, the dihedral angles between the acetate group and the two aromatic subunits (benzimidazole and nitro-phenyl-hydrazone) are 7.35 (9) and 18.23 (9)°, respectively. Intra-molecular N-H⋯O and N-H⋯N contacts occur. In the cr...
