Crystal structure and Hirshfeld surface analysis of diethyl 2-4-(4-fluoro­phen­yl)-2-methyl-4-oxobutan-2-ylmalonate

摘要

The title compound, C18H23FO5, was synthesized by reacting diethyl malonate with 1-(4-fluoro­phen­yl)-3-methyl­but-2-en-1-one. The mol­ecule adopts a loose conformation stabilized by weak C—H⋯O and C—H⋯π inter­actions. In the crystal, the mol­ecules are joined by C—H⋯O contacts into infinite chains along the b-axis direction with a C(6) graph-set motif. Hirshfeld surface analysis and fingerprint plots demonstrate the predominance of H⋯H, O⋯H and F⋯H inter­molecular inter­actions in the crystal structure.
