Abstract

The title compound, C23H24O5, a bis­(3,4-dimethoxy­phen­yl)­cyclo­penta­none derivative related to curcumin, shows noncrystallographic C2v symmetry with two noncrystallographic mirror planes inter­secting the cyclo­penta­none ring, resulting in a noncrystallographic twofold axis along the C=O double bond. The mol­ecule is basically planar, the angles between the planes of the cyclo­penta­none ring and those of the two benzene rings being 2.5 (3) and 1.2 (7)°. The dihedral angles of both meth­oxy groups with the benzene rings are nearly identical [179.05 (11), 177.88 (11), −172.51 (12) and 176.11 (13)°]. The two 3,4-dimethoxy­phenyl groups also lie within the plane of the mol­ecule and the angle between them is 1.4 (1)°. The crystal packing is stabilized by inter­molecular C—H⋯O hydrogen bonds.
