[2-(3,4-Dimethyl-benzo-yl)phen-yl](4-meth-oxy-phen-yl)methanone.

ABSTRACT: The title mol-ecule, C23H20O3, is disordered with a 180° rotation about an axis normal to the length of the mol-ecule, with the major and minor components in a 0.545?(5):0.455?(5) ratio. In the major component, the central benzene ring forms dihedral angles of 72.34?(3) and 69.46?(3)° with the dimethyl-substituted and meth-oxy-substituted benzene rings, respectively. Moreover, the central benzene ring forms dihedral angles of 50.86?(5) and 58.43?(4)° with the mean planes of the ketone groups. In the minor component, the corresponding dihedral angles between the benzene rings are 71.36?(4) and 67.94?(4)° and the dihedral angles between the benzene ring and the ketone groups are 56.44?(9) and 55.51?(8)°. In the crystal, C-H?O inter-actions generate a C(9) chain along the a-axis direction.
