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.
