(E)-3-(3-Chloro­phen­yl)-1-(4-methoxy­phen­yl)prop-2-en-1-one

The title mol­ecule, C₁₆H₁₃ClO₂, is trans with respect to the C=C double bond. The dihedral angles between the mean plane of the prop-2-en-1-one unit and those of the 3-chloro- and 4-meth­oxy-substituted benzene rings are 20.93 (9) and 20.42 (10)°, respectively, and the dihedral angle between the mean planes of the two benzene rings is 40.96 (5)°. The crystal structure is stabilized by weak inter­molecular C—H...O hydrogen bonds, forming chains along the b axis.
