Abstract: In the title compound, C36H28O4, the 1-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 76.59 (4)°. The dihedral angles between the central 2,7-diethoxynaphthalene ring system and the terminal naphthalene ring systems are 86.48 (4) and 83.97 (4)°. In the crystal, C-H...[pi] interactions between the central naphthalene ring systems and the naphthoyl groups are observed along the a axis, with the molecules forming a columnar structure. The columns are linked into chains parallel to the b axis by C-H...O interactions.
