Abstract: In the molecular structures of a series of substituted chalcones, namely (2E)-3-(2-fluoro-4-phenoxyphenyl)-1-phenylprop-2-en-1-one, C₂₁H₁₅FO₂, (I), (2E)-3-(2-fluoro-4-phenoxyphenyl)-1-(4-fluorophenyl)prop-2-en-1-one, C₂₁H₁₄F₂O₂, (II), (2E)-1-(4-chlorophenyl)-3-(2-fluoro-4-phenoxyphenyl)prop-2-en-1-one, C₂₁H₁₄ClFO₂, (III), (2E)-3-(2-fluoro-4-phenoxyphenyl)-1-(4-methylphenyl)prop-2-en-1-one, C₂₂H₁₇FO₂, (IV), and (2E)-3-(2-fluoro-4-phenoxyphenyl)-1-(4-methoxyphenyl)prop-2-en-1-one, C₂₂H₁₇FO₃, (V), the configuration of the keto group with respect to the olefinic double bond is s-cis. The molecules pack utilizing weak C-HO and C-H [pi] intermolecular contacts. Identical packing motifs involving C-HO interactions, forming both chains and dimers, along with C-H [pi] dimers and [pi] - [pi] aromatic interactions are observed in the fluoro, chloro and methyl derivatives.

Formula: C₂₁H₁₅FO₂, C₂₁H₁₄F₂O₂, C₂₁H₁₄ClFO₂, C₂₂H₁₇FO₂ and C₂₂H₁₇FO₃
