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

The title bis-chalcone compound, C24H16Cl2O2, crystallizes with one half-molecule in the asymmetric unit. The molecule has crystallographic inversion symmetry and lies about an inversion centre at the centroid of the central benzene ring. The olefinic double bonds adopt E configurations. The s-trans conformation of the central C—C bond of the enone group is confirmed by a C—C—C=C torsion angle of −162.88 (17)°.
