title: Bis(1-benzoyl-7-meth-oxy-naphthalen-2-yl) terephthalate.
abstract: The title molecule, C44H30O8, lies about a crystallographic inversion centre located at the centre of the central benzene ring. The benzene rings in the benzoyl and the terephthalate units make dihedral angles of 67.05 (7)° and 57.57 (7)°, respectively, with the naphthalene ring system. There is an intra-molecular C-H⋯O inter-action between the ketonic carbonyl O atom and an H atom on the naphthalene ring system. In the crystal, C-H⋯O inter-action of the benzene ring in the benzoyl group and weak C=O⋯π inter-action [O⋯centroid = 3.375 (2) Å] of the naphthalene ring with the O atom in the ketonic carbonyl group are observed. These inter-actions form layers parallel to the bc plane.
