In the molecular structures of a series of substituted chalcones, namely $(2E)$-3-(2-fluoro-4-phenoxyphenyl)-1-phenylprop-2-en-1-one, $C_{21}H_{15}FO_2$, (I), $(2E)$-3-(2-fluoro-4-phenoxyphenyl)-1-(4-fluorophenyl)prop-2-en-1-one, $C_{21}H_{14}F_2O_2$, (II), $(2E)$-1-(4-chlorophenyl)-3-(2-fluoro-4-phenoxyphenyl)prop-2-en-1-one, $C_{21}H_{14}C_lFO_2$, (III), $(2E)$-3-(2-fluoro-4-phenoxyphenyl)-1-(4-methylphenyl)prop-2-en-1-one, $C_{22}H_{17}FO_2$, (IV), and $(2E)$-3-(2-fluoro-4-phenoxyphenyl)-1-(4-methoxyphenyl) prop-2-en-1-one, $C_{22}H_{17}FO_3$, (V), the configuration of the keto group with respect to the olefinic double bond is s-cis. The molecules pack utilizing weak $C-H...O$ and $C-H...\pi$ intermolecular contacts. Identical packing motifs involving $C-H...O$ interactions, forming both chains and dimers, along with $C-H...\pi$ dimers and \pi - \pi aromatic interactions are observed in the uoro, chloro and methyl derivatives.
