Crystal structure and Hirshfeld surface analysis of (2 E ,2' E )-3,3'-(1,4-phenyl-ene)bis-[1-(2,4-di-fluoro-phen-yl)prop-2-en-1-one]

The asymmetric unit of the title compound, C H F O , comprises of one and a half mol-ecules; the half-mol-ecule is completed by crystallographic inversion symmetry. In the crystal, mol-ecules are linked into a three-dimensional network by C-H⋯F and C-H⋯O hydrogen bonds. Some of the C-H⋯F links are unusually short (< 2.20 Å). Hirshfeld surface analyses ( surfaces and two-dimensional fingerprint plots) for the title compound are presented and discussed.
