3-(3,4-Dimethoxy­phen­yl)-1-(4-fluoro­phen­yl)prop-2-en-1-one

The title compound, C17H15FO3, crystallizes in a centrosymmetric space group and thus does not show any non-linear optical activity. There are two molecules in the asymmetric unit.

Do C—H⋯O and C—H⋯π inter­actions help to stabilize a non-centrosymmetric structure for racemic 2,3-dibromo-1,3-diphenyl­propan-1-one?

The racemic title compound, C15H12Br2O, crystallizes in a non-centrosymmetric structure and displays a significant non-linear optical response to red light. The crystal packing is influenced by C-H...O and C-H...pi interactions. One of the former bonds has a short H...O separation of 2.27 angstroms.

2,3-Dibromo-3-(4-methoxyphenyl)-1-phenylpropan-1-one

In the title compound, C16H14Br2O2, the C-Br bond lengths are dsignificantly different. One of the Br atoms participates in weak hydrogen-bonding interactions with C-H groups from adjoining molecules.

(2‐Chloro­anilino)acetophenone

The title compound, C(14)H(12)ClNO, is used in perfumery, as a catalyst for the polymerization of olefins, and in organic synthesis, especially as a photosensitizer and in the manufacture of dyes. The molecule is essentially planar and has a trans configuration. In this configuration, the Cl and O atoms shield the amino H atom, preventing the formation of an intermolecular hydrogen bond.
