The molecule is almost planar, with the phenyl ring inclined to the isoxazole ring by 0.5(1)°. The ester moiety has an extended conformation and is almost in the same plane with respect to the isoxazole ring, as indicated by the O - C - C - N torsion angle of -172.86(18)°. In the crystal, molecules are linked via pairs of C-H⋯O hydrogen bonds with the same acceptor atom, forming inversion dimers with two R 2<sup>1</sup>(7) ring motifs. The molecules stack in layers lying parallel to (10-3). Analysis using Hirshfeld surface generation and two-dimensional fingerprint plots explores the distribution of weak intermolecular interactions in the crystal structure.truecrystal structure | drug intermediate | Hirshfeld surface | hydrogen bonding | isoxazole derivativeCrystal structure and Hirshfeld surface analysis of ethyl 5-phenylisoxazole-3-carboxylateArticlehttp://journals.iucr.org/e/issues/2017/04/00/su5350/su5350.pdf20569890531-53420175arJournal0
