Deskripsi

Crystals of the title compound, C16H12N2O4, were obtained accidentally from a hydrothermal reaction of 5-[(1H-benzimidazol-1-yl)methyl]isophthalic acid with manganese bromide in the presence of N,N′-dimethylformamide. In the title molecule, the benzimidazole ring system is almost planar, with a maximum deviation from the mean plane of 0.010 (2) Å. The benzimidazole and central benzene rings are inclined at a dihedral angle of 71.7 (6)°. The crystal structure is stabilized by O—H...N and O—H...O hydrogen bonds.
