6-[(2,4-Dimethylanilino)methylidene]-2-hydroxycyclohexa-2,4-dienone

Abstract

In the title compound, C15H15NO2, the dihedral angle between the aromatic rings is 5.86 (6)°, and an intramolecular N—H...O hydrogen bond generates an S(6) motif, which helps to stabilize the enamine–keto tautomer. An intramolecular O—H...O hydrogen bond also occurs. In the crystal, inversion dimers linked by pairs of O—H...O hydrogen bonds generate R22(10) loops. A C—H...O interaction links the dimers into [010] chains and aromatic π–π stacking [centroid–centroid separation = 3.6131 (9) Å] also occurs.
