title: {2,7-Dimeth-oxy-8-[4-(2-methyl-prop-yl)benzo-yl]naphthalen-1-yl}[4-(2-methyl-prop-yl)phen-yl]methanone.
abstract: In the mol-ecule of the title compound, C34H36O4, the two 4-isobutyl-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, and the benzene rings make a dihedral angle of 21.59 (7)°. The dihedral angles between the benzene rings and the naphthalene ring system are 69.26 (6) and 64.29 (5)°. There are no classical hydrogen bonds in the structure, but inversion-related mol-ecules engage in π-π stacking, with an inter-planar spacing between related naphthalene groups of 3.4120 (16) Å.
