2-Hydr­oxy-6-[(1-napthyl­amino)­methylene]­cyclo­hexa-2,4-dien-1-one

The mol­ecule of the title compound, C₁₇H₁₃NO₂, is nearly planar and exists in the keto–amine (N—H...O) tautomeric form, with a strong intra­molecular hydrogen bond of 2.576 (2) Å between the O and N atoms. The mol­ecules are linked by O—H...O hydrogen bonds to form dimers, and are further linked by C—H...π inter­actions, forming a three-dimensional network.
