In the mol-ecule of the title compound, CHNO, the isoxazol and phenyl rings are oriented at a dihedral angle of 14.84 (5)°. The 2-cyano-acrylate moiety is in - configuration. In the crystal, there are no inter-molecular hydrogen-bonding or C-H⋯π(ring) inter-actions, only a π-π inter-action 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%) inter-actions.

在标题化合物CHNO的分子中，异恶唑环和苯环以14.84 (5)°的二面角取向。2-氰基丙烯酸酯部分呈 - 构型。在晶体中，不存在分子间氢键或C-H⋯π(环)相互作用，仅在平行的异恶唑环之间存在π-π相互作用，质心到质心距离为3.4932 (9) Å（α = 0.02°）。 Hirshfeld表面分析表明，对晶体堆积最重要的贡献来自H⋯H（43.9%）、H⋯N/N⋯H（17.0%）、H⋯O/O⋯H（13.9%）和C⋯C（10.1%）相互作用。
