Abstract

In the title mol-ecule {systematic name: [2,7-dimethoxy-8-(4-phenoxybenzoyl)naphthalen-1-yl](4-phenoxyphenyl)methan-one}, C(38)H(28)O(6), the 4-phen-oxy-benzoyl units adopt a syn orientation with respect to the naphthalene ring system. The inter-nal benzene rings, A and B, make dihedral angles of 86.72 (5) and 79.22 (5)° with the naphthalene ring system. The two terminal benzene rings, C and D, of the 4-phen-oxy-benzoyl groups are twisted with respect to benzene rings A and B, with dihedral angles of A/C = 62.72 (8) and B/D = 87.61 (6)°. In the crystal, H atoms in the naphthalene system make two types of inter-molecular C-H⋯O inter-actions with the carbonyl O atom and the phenyl etheral O atom of neighbouring mol-ecules. Mol-ecules are further linked by C-H⋯π inter-actions involving a H atom of terminal benzene ring D and the π-system of the inter-nal benzene ring A, forming dimers centered about an inversion center.
