(2E,2′E)-3,3′-(1,4-Phenylene)bis[1-(4-fluorophenyl)prop-2-en-1-one]

Abstract

The title bis-chalcone compound, C24H16F2O2, crystallizes with one half-molecule in the asymmetric unit. The molecule lies about an inversion centre at the centroid of the central benzene ring. The olefinic double bonds adoptEconformations. In the crystal, C—H...O hydrogen bonds form sheets of molecules in theacplane and C—H...F hydrogen bonds form zigzag chains along thea-axis direction. These combine to generate a three-dimensional network of molecules stacked along thec-axis direction.
