Crystal structure of ethyl 2-(1H-benzimidazol-2-yl)-2-[2-(4-nitrophenyl)hydrazinylidene]acetate
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...

The title compound, C(13)H(9)N(3)O(3), was prepared by the reaction of 5-nitro-salicyl-aldehyde with 1,2-diamino-benzene in methanol. The whole mol-ecule is approximately planar, with a mean deviation from the plane defined by the non-H atoms of 0.0311 (4) Å, and with a dihedral angle between the benzene ring and the benzimidazole ring system of 1.1 (3)°. An intra-molecular O-H⋯N hydrogen bond ...

A new benzimidazole compound, C(12)H(14)N(2)O(2), has been synthesized by the reaction of 2-methyl-1H-benzimidazole and ethyl 2-bromo-acetate. In the crystal structure, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into chains. π⋯π Contacts (centroid⋯centroid distance = 3.713 Å) are observed. A C-H⋯π inter-action is also present. The N-C-C-O torsion angle is 178.4 (2)°.

The mol-ecule of the title compound, C(14)H(9)N(3), is essentially planar, the dihedral angle formed by the benzimidazole ring system with the benzene ring being 3.87 (3)°. In the crystal packing, mol-ecules are linked into zigzag chains running parallel to the b axis by inter-molecular N-H⋯N hydrogen-bond inter-actions.
متن کامل2-(1H-Benzimidazol-2-yl)phenol
The title mol-ecule, C13H10N2O, is essentially planar, the maximum deviation from the plane of the non-H atoms being 0.016 (2) Å. The imidazole ring makes a dihedral angle of 0.37 (13)° with the attached benzene ring. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through N-H⋯O hydrogen bonds, forming chains propagating in [001]. The c...
