1-(3,4-Dimethoxyphenyl)-3-phenylprop-2-en-1-one

Abstract

In the title compound, C17H16O3, the dihedral angle between the mean planes of the benzene rings is 57.1 (1)°. The mean plane of the ketone group is twisted by 10.0 (5)° from that of the dimethoxyphenyl ring. The two dimethoxyphenyl groups are twisted slighly from the mean plane of the phenyl ring, with C—O—C—C torsion angles of 6.4 (2) and −7.9 (2)° [r.m.s. deviations = 0.15 (3) and 0.18 (3) Å for the two methoxy C atoms]. In the crystal, weak centroid–centroid π–π stacking interactions, with intercentroid distances of 3.8939 (11) and 3.9430 (10) Å are observed.
