چکیده
The title Schiff base compound, C34H24N2O3, was prepared by a condensation reaction of bifunctional aromatic diamine (4,4'-diamino-diphenyl ether) with hy-droxy-naphtaldehyde. The asymmetric unit contains two independent mol-ecules with similar conformations. The compound contains a central oxygen bridge and two functionalized [(E)-(phenyl-iminio)meth-yl]naphthalen-2-olate units. The dihedral angles between the benzene rings linking to the central O atom are 74.64 (19) and 69.85 (18)° in the two independent mol-ecules. Intra-molecular O-H⋯O hydrogen bonding occurs between the protonated imino N atoms and deprotonated hy-droxy O atoms in both mol-ecules. In the crystal, weak C-H⋯O hydrogen bonds are observed.
