2,2′-[1,1′-(Heptane-1,7-diyldioxydinitrilo)diethylidyne]di-1-naphthol

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.
