2-Hydroxy-6-[(2-Hydroxyphenylamino)Methylene]-Cyclohexa-2,4-Dienone

Abstract

The title compound, C<inf>13</inf>H<inf>11</inf>NO<inf>3</inf>, adopts the keto-amine tautomeric form, with the H atom located on N rather than on O. This H atom is involved in a strong intramolecular hydrogen bond. There are two independent molecules in the asymmetric unit. The molecules are linked by intramolecular N-H⋯O and O-H⋯O and intermolecular O-H⋯O hydrogen bonds into a three-dimensional network. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
