N-(4,6-Dimethylpyrimidin-2-yl)-1H-benzimidazol-2-amine

Abstract

There are two independent molecules in the asymmetric unit of the title compound, C13H13N5. In each molecule, an amino N atom is connected to a benzimidazole fused-ring system and a pyrimidine ring [these are aligned at 1.3 (1)° in one independent molecule and at 5.4 (1)° in the other]. The amino N atom of the fused ring forms an intramolecular N - H⋯O hydrogen bond to a pyrimidine N atom in each molecule. The amino N atom connecting the two ring systems interacts with the other N atom of the pyrimidine ring of an adjacent molecule, generating centrosymmetric hydrogen-bonded dimers.
