(E)-3-(2-Chloro-phen-yl)-1-(4-chloro-phen-yl)prop-2-en-1-one

Abstract

The title compound, C15H10Cl2O, adopts an E configuration with respect to the C=C bond of the propenone unit. The dihedral angle between the two benzene rings is 32.4 (1)°. Intra-molecular C - H⋯O and C - H⋯Cl hydrogen bonds generate an S(5)S(5)S(5) motif. In addition, the crystal structure is stabilized by weak inter-molecular C - H⋯O hydrogen bonds.
