Crystal structure of 2-{[(5-nitrothiophen-2-yl)methylidene]amino}phenol

Abstract

The title compound, C11H8N2O3S, 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 R22(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 three-dimensional network.
