Crystal structure and Hirshfeld surface analysis of (2)-3-(4-chloro-3-fluoro-phen-yl)-1-(3,4-di-meth-oxy-phen-yl)prop-2-en-1-one.

The mol-ecular structure of the title compound, CHClFO, consists of a 4-chloro-3-fluoro-phenyl ring and a 3,4-di-meth-oxy-phenyl ring linked a prop-2-en-1-one spacer. The mol-ecule has an configuration about the C=C bond and the carbonyl group is with respect to the C=C bond. The F and H atoms at the positions of the 4-chloro-3-fluoro-phenyl ring are disordered over two orientations, with an occupancy ratio of 0.785 (3):0.215 (3). In the crystal, mol-ecules are linked pairs of C-H⋯O inter-actions with an (14) ring motif, forming inversion dimers. The dimers are linked into a tape structure running along [10] by a C-H⋯π inter-action. The inter-molecular contacts in the crystal were further analysed using Hirshfield surface analysis, which indicates that the most significant contacts are H⋯H (25.0%), followed by C⋯H/H⋯C (20.6%), O⋯H/H⋯O (15.6%), Cl⋯H/H⋯Cl (10.7%), F⋯H/H⋯F (10.4%), F⋯C/C⋯F (7.2%) and C⋯C (3.0%).
