Ethyl (2Z)-3-(4-chlorophenyl)-2-cyano-3-(methoxyamino)prop-2-enoate was prepared by reacting the lithium salt of ethyl cyanoacetate with (Z)-O-methyl-4-chloroben-zohydroximoyl fluoride. This compound crystallizes in space group Pbca,with lattice constants a=7.5740(15) ?, b=11.337(2) ?, and c=30.424(5) ? at 110 K. Characterizations include spectrometric identifications employing IR, UV, and ¹H and ¹³C NMR. The compound exists in the solid as the enamine tautomer, with the cyano group cis to the 4-chlorophenyl group (the Z configuration). The C=C and C–N bond distances are 1.3930(16) ? and 1.3278(16) ?, respectively. The N–H group forms a bifurcated hydrogen bond with acceptors C=O (intramolecular) and C≡N (intermolecular).Supplementary material CCDC-289444 contains the supplementary crystallographic data for this paper.

The solid-state structure displays an intramolecular S(6) hydrogen bond and the crystal architecture is maintained by intermolecular F?H, O?H, and C?C short contacts. A DFT geometry optimization is compared with the experimental structure. As ¹⁹F NMR spectroscopy can be used for metabolic tagging of biologically active compounds (including chalcones), the solution-state ¹⁹F chemical shift and ¹³C¹⁹F coupling constants (ⁿJ) are also reported.
