The title compound, CHFO, was synthesized by reacting diethyl malonate with 1-(4-fluoro-phen-yl)-3-methyl-but-2-en-1-one. The mol-ecule adopts a loose conformation stabilized by weak C-H⋯O and C-H⋯π inter-actions. In the crystal, the mol-ecules are joined by C-H⋯O contacts into infinite chains along the axis direction with a (6) graph-set motif. Hirshfeld surface analysis and fingerprint plots demonstrate the predominance of H⋯H, O⋯H and F⋯H inter-molecular inter-actions in the crystal structure.
标题化合物CHFO是通过丙二酸二乙酯与1-(4-氟苯基)-3-甲基-丁-2-烯-1-酮反应合成的。该分子采用由弱C-H⋯O和C-H⋯π相互作用稳定的松散构象。在晶体中，分子通过C-H⋯O接触沿轴方向连接成具有(6)图集 motif的无限链。Hirshfeld表面分析和指纹图谱表明晶体结构中H⋯H、O⋯H和F⋯H分子间相互作用占主导地位。
