Abstract

In the title mol-ecule, C(30)H(28)O(4), the inter-planar angle between the two benzene rings of the 3,5-dimethyl-benzoyl groups is 50.35 (7)°. The dihedral angles between the two benzene rings and the naphthalene ring system are 81.87 (6) and 83.55 (6)°. In addition, the conformations of the pairs of methyl groups and their counterparts differ from each other though their environment is very similar. In the crystal, weak C-H⋯O inter-actions occur.
