✦ Synopsis

The centrosymmetric title compound, C 24 H 34 N 4 O 4 , has been characterized structurally by 1 H NMR and X-ray crystallography. The two benzene rings are parallel to each other. The compound forms intramolecular hydrogen bonds, where the oxime group acts as a hydrogen-bond donor and the OH group acts as a hydrogen-bond acceptor.
