Abstract
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 intra-molecular C-H⋯F hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked into a three-dimensional network by C-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions are also observed [centroid-centroid separation = 3.5629 (18) Å]. The inter-molecular inter-actions in the crystal structure were qu-anti-fied and analysed using Hirshfeld surface analysis.
