title: 2-[(1H-Benzimidazol-2-yl)imino-meth-yl]-4,6-dibromo-phenol ethanol hemisolvate.
abstract: The title compound, C14H9Br2N3O·0.5C2H5OH, crystallizes with two 2-[(1H-benzimidazol-2-yl)imino-meth-yl]-4,6-dibromo-phenol mol-ecules and one ethanol solvent mol-ecule in the asymmetric unit. The benzene and benzimidazole rings subtend dihedral angles of 4.5 (3) and 5.2 (2)° in the two mol-ecules. In the crystal, one mol-ecule presents π-π stacking with the equivalent mol-ecule related by inversion, at a distance of 3.30 Å (separation between mol-ecular mean planes). A three-dimensional network is formed through N-H⋯N, N-H⋯O and O-H⋯N hydrogen bonds.
