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

摘要

The title bis-chalcone compound, C24H16F2O2, crystallizes with one halfmolecule\udin the asymmetric unit. The molecule lies about an inversion centre at\udthe centroid of the central benzene ring. The olefinic double bonds adopt E\udconformations. In the crystal, C—H...O hydrogen bonds form sheets of\udmolecules in the ac plane and C—H...F hydrogen bonds form zigzag chains\udalong the a-axis direction. These combine to generate a three-dimensional\udnetwork of molecules stacked along the c-axis direction.
