چکیده
The asymmetric unit of the title compound, C(19)H(12)Cl(2)O, contains four independent mol-ecules, which can be divided into two pairs of mol-ecules with close values of the C-C(=O)-C=C torsion angles in each pair, viz. 165.12 (16) and 165.68 (15)° in one pair, and -164.66 (15) and -164.81 (15)° in the other pair. The crystal packing exhibits short inter-molecular Cl⋯Cl contacts of 3.362 (1) Å.

The mol-ecule of the title compound, C(15)H(9)BrCl(2)O, is shown to be the E isomer, with the 3,4-dichloro-benzoyl and p-bromo-phenyl substituents in trans positions with respect to the chalcone olefin bond. The mol-ecule is non-planar, the two aromatic rings forming a dihedral angle of 49.58 (1)°.

In the title compound, C(15)H(10)Cl(2)O(2), the dihedral angle between the mean planes of the two benzene rings is 7.7 (6)°. The crystal packing is influenced by O-H⋯O hydrogen bonds, which form chains along [010]. Weak π-π stacking inter-actions [centroid-centroid distance = 3.6697 (13) Å] are observed, which may contribute to the crystal packing stability.

In the title compound, C(20)H(15)BrO(2), the prop-2-en-1-one fragment is substanti-ally twisted [C-C-C-O = 23.0 (11)°]. The dihedral angle between the benzene and naphthalene rings is 44.28 (13)°. The only possible directional inter-actions in the crystal are weak C-H⋯π contacts, which generate (001) sheets.
