(2E)-1-(3-Chloro-phen-yl)-3-(4-chloro-phen-yl)prop-2-en-1-one.

ABSTRACT: The title compound, C(15)H(10)Cl(2)O, is a chalcone with 3-chloro-phenyl and 4-chloro-phenyl substituents bonded at the opposite ends of a propenone group, the biologically active region. The dihedral angle between mean planes of these two chloro-substituted benzene rings is 46.7?(7)° compared to 46.0?(1) and 32.4?(1)° in similar published sructures. The angles between the mean plane of the prop-2-en-1-one group and the mean planes of the 3-chloro-phenyl and 4-chloro-phenyl rings are 24.1?(2) and 29.63°, respectively. While no classical hydrogen bonds are present, weak inter-molecular C-H??-ring inter-actions are observed, which contribute to the stability of crystal packing.
