Abstract
The title compound, C14H9Br2N3O·0.5C2H5OH, crystallizes with two 2-[(1H-benzimidazol-2-yl)iminomethyl]-4,6-dibromophenol molecules and one ethanol solvent molecule in the asymmetric unit. The benzene and benzimidazole rings subtend dihedral angles of 4.5 (3) and 5.2 (2)° in the two molecules. In the crystal, one molecule presents π–π stacking with the equivalent molecule related by inversion, at a distance of 3.30 Å (separation between molecular mean planes). A three-dimensional network is formed through N—H⋯N, N—H⋯O and O—H⋯N hydrogen bonds.
