Abstract: In the title compound, C36H28O4, the two 2-naphthoyl groups at the 1- and 8-positions of the central 2,7-diethoxynaphthalene ring system are aligned almost antiparallel and make a dihedral angle of 48.35 (5)°. The dihedral angles between the central 2,7-diethoxynaphthalene ring system and the terminal naphthalene ring systems are 77.64 (4) and 73.73 (4)°. In the crystal, molecules are linked into chains along the a-axis direction by dual C-HO interactions between naphthoyl groups.
