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

Abstract

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