[8-(4-Chloro-benzo-yl)-2,7-dimeth-oxy-naphthalen-1-yl](2,4,6-trimethyl-phen-yl)methanone

Abstract

In the title compound, C(29)H(25)ClO(4), the dihedral angle between the benzene rings of the 2,4,6-trimethyl-benzoyl group and the 4-chloro-benzoyl group is 65.19 (9)°. The dihedral angles between the naphthalene ring system and the benzene rings of the 2,4,6-trimethyl-benzoyl group and the 4-chloro-benzoyl group are 85.66 (8) and 69.48 (8)°, respectively. In the crystal, two types of inter-molecular C-H⋯O inter-actions and an intra-molecular C-H⋯O inter-action are observed. Moreover, there is a short intra-molecular C=O⋯C=O contact of 2.614 (2) Å between the benzoyl substituents.
