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)degrees. An intramolecular O-H center dot center dot center dot N hydrogen bond generates an S(5) ring motif. In the crystal, molecules are linked into centrosymmetric dimers by pairs of O-H center dot center dot center dot O hydrogen bonds with an R-2(2)(22) graph-set motif. Aromatic pi-pi stacking interactions [centroid-centroid separations = 3.653 (3) and 3.852 (3) angstrom] link the dimers into a three-dimensional network.
