摘要：

The crystal structure of the title compound, C(16)H(13)ClO(2) (II), (space group P2(1)/c,) is a polymorph of the structure, (I), reported by Harrison, Yathirajan, Sarojini, Narayana & Indira [Acta Cryst. (2006), E62, o1647-o1649] in the orthorhombic space group Pna2(1). The dihedral angle between the mean planes of the 4-chloro- and 4-methoxy-substituted benzene rings is 52.9 (1)degrees in (II) compared to 21.82 (6)degrees for polymorph (I). The dihedral angles between the mean planes of the prop-2-en-1-one group and those of the 4-chlorophenyl and 4-methoxyphenyl rings are 23.3 (3) and 33.7 (1)degrees, respectively. in (II). The corresponding values are 17.7 (1) and 6.0 (3)degrees, respectively, in polymorph (I). In the crystal, weak C-H center dot center dot center dot pi interactions are observed.
