(E)-3-[(4-Butylphenyl)iminomethyl]benzene-1,2-diol

Abstract

The title compound, C17H19NO2, exists as an enol–imine tautomer. The dihedral angle between the two benzene rings is 4.6 (2)°. The molecular structure is stabilized by intramolecular O—H...O and O—H...N hydrogen bonds which generate S(5) and S(6) ring motifs, respectively. In the crystal, molecules are linked into centrosymmetric dimers by pairs of O—H...O hydrogen bonds. In addition, C—H...π interactions involving both benzene rings are observed.
