Crystal structure and Hirshfeld surface analysis of ethyl 5-phenyl-isoxazole-3-carboxyl-ate.

ABSTRACT: The title compound, C12H11NO3, is an inter-mediate used in the synthesis of many drug-like mol-ecules. The mol-ecule 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, mol-ecules are linked via pairs of C-H?O hydrogen bonds with the same acceptor atom, forming inversion dimers with two R21(7) ring motifs. The mol-ecules stack in layers lying parallel to (10-3). Analysis using Hirshfeld surface generation and two-dimensional fingerprint plots explores the distribution of weak inter-molecular inter-actions in the crystal structure.
