2-[(1H-Benzimidazol-2-yl)imino­meth­yl]-4,6-dibromo­phenol ethanol hemisolvate

J. Liu, Z. Liu and S. Yuan

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 [pi]-[pi] 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.
