Abstract

The title Schiff base compound, C33H30N 4O4·H2O, adopts an E configuration with respect to each C=N double bond. In the molecule, there are naphthoxide anions and the protonated imino N atoms. intramolecular N-H⋯O hydrogen bonds lead to the formation of approximately planar (maximum deviation 0.029 Å for H atom) six-membered rings.. In the crystal, molecules are linked by O-H⋯O and N-H⋯O hydrogen bonds as well as C - H⋯O contacts, leading to the formation of a three-dimensional network..
