Crystal structure of the chalcone (E)-3-(furan-2-yl)-1-phenylprop-2-en-1-one

Abstract

The title chalcone derivative, C13H10O2, adopts an E conformation about the C=C double bond. The molecule is composed of a furanyl and a phenyl ring, bridged by an α,β-unsaturated carbonyl system, which are inclined to one another by 24.07 (7)°. In the crystal, molecules are connected by weak C—H...O hydrogen bonds involving the carbonyl O atom acting as a trifurcated acceptor and C—H...π interactions, forming ribbons extending along the c-axis direction.
