Crystal structure and Hirshfeld surface analysis of (E)-3-(2-chloro-6-fluorophenyl)-1-(3-fluoro-4-methoxyphenyl)prop-2-en-1-one

In the title chalcone derivative, C16H11ClF2O2, the enone group adopts an E conformation. The dihedral angle between the benzene rings is 0.47 (9)° and an intramolecular C—H...F hydrogen bond closes an S(6) ring. In the crystal, molecules are linked into a three-dimensional network by C—H...O hydrogen bonds and aromatic π–π stacking interactions are also observed [centroid–centroid separation = 3.5629 (18) Å]. The intermolecular interactions in the crystal structure were quantified and analysed using Hirshfeld surface analysis
