Abstract: The title compound, C26H20O4, has an asymmetrical conformation at 193 K. The 4-acetylphenyl groups are twisted away from the the naphthalene ring system, with one benzene ring turned towards the 1-position of the naphthalene ring and the other benzene ring turned towards the 6-position. The interplanar angles between the mean planes of the benzene rings and the naphthalene ring system are 68.71 (6) and 74.01 (6)°. The structure displays C-H
O hydrogen bonding and
-
stacking interactions [centroid-centroid and interplanar distances are 3.5938 (9) and 3.517 Å, respectively].
