4-[(3-Chloro­phenyl)­diazenyl]-6-Methoxy-2-{[Tris­(Hydroxy­methyl)­methyl]­Aminomethyl­ene}Cyclo­hexa-3,5-Dien-1(2H)-One

Abstract

The title compound, C18H20ClN3O5, adopts the keto-amine tautomeric form and displays an intramolecular N-H...O hydrogen bond. The configuration around the azo N=N double bond is trans and the dihedral angle between the two aromatic rings is 10.0 (1)degrees. Intermolecular O-H...O hydrogen bonds form a three-dimensional network.
