In the title compound, C(4)H(5)N(3)O(2), the nitro group is twisted with respect to the imidazole ring by a dihedral angle of 5.60 (2)°. Weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonding is present in the crystal structure.

The structure of the title compound, C(8)H(9)N(3), a potential anti-tumour drug, was determined in order to give more insight into its structure-function relationships. The benzimidazole core of the mol-ecule was found to be exactly planar, while the substituents are displaced slightly from the mol-ecular plane [C-C-N-C and C-C-C-N torsion angles of 0.8 (3) and 179.0 (1)° for the methyl and ami...

In the title compound, C(4)H(4)N(4)O(4), the two nitro groups are twisted with respect to the imidazole plane, making dihedral angles of 24.2 (3) and 33.4 (4)°. In the crystal structure, the mol-ecules are linked through non-classical inter-molecular C-H⋯O hydrogen bonds.

In the title mol-ecule, C(4)H(6)N(8)S(2), two tetra-zole rings linked by a disulfide bridge form a dihedral angle of 71.32 (7)° [C-S-S-C torsion angle = -80.51 (10)°]. In the crystal, strong inter-molecular π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.285 (3) Å] link pairs of mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯N hydrogen bonds furt...
