D.-S. Yang

Abstract: The molecule of the title compound, C₁₈H₁₃N₃O₅, displays an E configuration with respect to the C=N double bond. The dihedral angle between the benzene ring and the naphthyl system is 1.1 (2)°. In the crystal structure, molecules are linked through intermolecular N-HO and O-HO hydrogen bonds, forming a three-dimensional network.
