{2,7-Dieth­oxy-8-[(naphthalen-1-yl)carbon­yl]naph­thalen-1-yl}(naphthalen-1-yl)methanone

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...π 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.
