Crystal Structure of 2-{[(5-nitro-thio-phen-2-yl)methyl-idene]amino}-phenol

Abstract

The title compound, C<inf>11</inf>H<inf>8</inf>N<inf>2</inf>O<inf>3</inf>S, is roughly planar; the dihedral angle between the planes of the thiophene and benzene rings is 8.38 (10)°. An intramolecular O-H⋯N hydrogen bond generates an S(5) ring motif. In the crystal, molecules are linked into centrosymmetric dimers by pairs of O-H⋯O hydrogen bonds with an R<inf>2</inf>2 (22) graph-set motif. Aromatic π - π stacking interactions [centroid-centroid separations = 3.653 (3) and 3.852 (3) Å] link the dimers into a threedimensional network.
