In the title compound, C11H9NO3, the phenyl and isoxazole rings form a dihedral angle of 56.64 (8)°. The carb-oxy group is almost in the same plane as the isoxazole ring with a C-C-C-O torsion angle of -3.3 (2)°. In the crystal, pairs of O-H⋯O hydrogen bonds link the mol-ecules into head-to-head dimers. C-H⋯N hydrogen bonds and π-π stacking inter-actions between phenyl rings [centroid-centroid distance = 3.9614 (17)Å] link the dimers into a three-dimensional network.
在标题化合物C₁₁H₉NO₃中，苯环和异恶唑环形成的二面角为56.64 (8)°。羧基与异恶唑环几乎处于同一平面，C-C-C-O扭转角为-3.3 (2)°。在晶体中，O-H⋯O氢键对将分子连接成头对头的二聚体。C-H⋯N氢键以及苯环之间的π-π堆积相互作用[质心-质心距离 = 3.9614 (17)Å]将二聚体连接成三维网络。
