【 摘 要 】

In the title compound, C14H9ClN2O3, the fused pyridine and isoxazole rings are approximately planar, making a dihedral angle of 1.14 (16)°. The mol­ecule is twisted with the benzene ring and the mean plane through the fused pyridine-isoxazole ring system being inclined to one another by 47.03 (13)°. There is an intra­molecular O—H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, mol­ecules are linked by C—H⋯N hydrogen bonds, forming chains propagating along [001]. The chains are linked by slipped parallel π–π inter­actions, involving inversion-related benzene rings, forming slabs lying parallel to the bc plane {inter-centroid distance = 3.770 (2) Å].
