Abstract: The title compound, C₂₈H₂₈N₂O₄, was synthesized by the reaction of 2-acetyl-1-naphthol with 1,4-bis(aminooxy)butane in ethanol. The molecule, which lies about an inversion centre, adopts a linear structure, in which the oxime groups and naphthalene ring systems assume an anti conformation. The intramolecular interplanar distance between parallel naphthalene rings is 1.054 (3) Å. Intramolecular O-HN hydrogen bonds are formed between the oxime nitrogen and hydroxy groups.
