A new perfluoromethylated vinylogous amide, (Z)‐4,4,4‐trifluoro‐1‐(2‐hydroxyphenyl)‐3‐(2‐methoxyethylamino)‐2‐buten‐1‐one, is chosen as an example to investigate the bonding interactions in solid state. The Z, s‐cis form is the dominant conformation in both solution and solid state. Intramolecular hydrogen bonding determines this conformational preference in a nonpolar solvent (NMR spectra). Carbonyl and phenol groups are sensitive to the intra‐ and intermolecular contacts (vibrational spectra). The supramolecular assembly (X‐ray diffraction) is governed by NH⋯O and OH⋯O strong intermolecular hydrogen bonds giving rise to center‐symmetric R22false(16false) and R22false(12false) graph‐set motifs. The π‐stacking, F⋯H and F⋯F interactions are also discussed (Hirshfeld analysis).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
