چکیده
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.
