Abstract

The mol­ecule of the title compound, C31H34N2O4, adopts an L-shaped configuration, in which the naphthalene units are approximately perpendicular, making a dihedral angle of 87.89 (3)°. Intramolecular H-bonds are formed between the OH substituents and the N atoms at each end of the molecule. In the crystal structure, each mol­ecule links six other mol­ecules into an infinite three-dimensional network supra­molecular structure, which is built from one-dimensional zigzag chains via weak C—H⋯π stacking and inter­molecular C—H⋯O hydrogen bonds.

Highlights

  • Intramolecular H-bonds are formed between the OH substituents and the N atoms at each end of the molecule

  • Each molecule links six other molecules into an infinite three-dimensional network supramolecular structure, which is built from one-dimensional zigzag chains via weak C—H stacking and intermolecular

  • The two intramolecular hydrogen bonds, O3—H3···N1 and O4—H4···N2, generate S(6) ring motifs helping to the stabilization of the title molecule (Fig. 2)
