3-(4-Acetyl­phenyl­imino­methyl)-1,2-di­hydroxy­benzene

The mol­ecule of the title compound, C₁₅H₁₃NO₃, is not planar and the dihedral angle between the planes of the two aromatic rings is 53.93 (7)°. The mol­ecule exists in the crystal structure in the phenol–imine tautomeric form and has two `active' H atoms, which participate in strong intramolecular O—H⋯N and O—H⋯O hydrogen bonds. One of the H atoms is also involved in an intermolecular hydrogen bond, which links the mol­ecules into centrosymmetric dimers.
