2-(1H-Benzimidazol-2-yl)-4-nitro-phenol.


ABSTRACT: 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 occurs. In the crystal, adjacent mol-ecules are linked through inter-molecular N-H?O hydrogen bonds, forming centrosymmetric dimers.
