Abstract

The mol-ecule of the title compound, C(26)H(20)O(4), is located on a twofold rotation axis. The two benzoyl groups are situated in an anti orientation. The dihedral angle between the mean planes of the phenyl ring and the naphthalene ring system is 80.25 (6)°. The phenyl and carbonyl groups in each benzoyl group are almost coplanar. The mol-ecular packing is stabilized by weak C-H⋯O hydrogen bonds and a π-π stacking inter-action between the phenyl rings [centroid-centroid and inter-planar distances of 3.6383 (10) and 3.294 Å, respectively].
