Synthesis, crystal structure and Hirshfeld surface analysis of ethyl (E)-2-cyano-3-[5-(4-ethylphenyl)isoxazol-3-yl]prop-2-enoate

In the molecule of the title compound, C 17 H 16 N 2 O 3 , the isoxazol and phenyl rings are oriented at a dihedral angle of 14.84 (5)°. The 2-cyanoacrylate moiety is in E - configuration. In the crystal, there are no intermolecular hydrogen-bonding or C—H...π(ring) interactions, only a π–π interaction between the parallel isoxazol rings with centroid-to-centroid distance of 3.4932 (9) Å (α = 0.02°). The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H...H (43.9%), H...N/N...H (17.0%), H...O/O...H (13.9%) and C...C (10.1%) interactions.
