Abstract
The title compound, C19H23N3O5, adopts the keto-amine tautomeric form with the hydroxy H atom located on the N atom, where it is involved in a strong intramolecular N H center dot center dot center dot O hydrogen bond. The compound exhibits trans geometry with respect to the azo N=N double bond, with a dihedral angle between the two benzene rings of 38.03 (6)degrees. The packing of the molecules in the crystal structure is determined by O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds. A comparison with closely related compounds is given.
