2,5-Bis(4-chlorobenzylidene)cyclopentanone

Abstract

The title bis-chalcone compound, C19H14Cl2O, crystallizes with one half-molecule in the asymmetric unit. The molecule has crystallographic mirror symmetry with the C=O bond on the mirror plane. The molecule adopts anEconfiguration about the central olefinic bonds. In the crystal, molecules are linkedviaweak C—H...O hydrogen bonds, forming supramolecular chains propagating along the [100] direction.
