title: Crystal structure of (5-chloro-2-hy-droxy-phen-yl)(3-methyl-isoxazolo[5,4-b]pyridin-5-yl)methanone.
abstract: In the title compound, C14H9ClN2O3, the fused pyridine and isoxazole rings are approximately planar, making a dihedral angle of 1.14 (16)°. The mol-ecule 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 intra-molecular O-H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains propagating along [001]. The chains are linked by slipped parallel π-π inter-actions, involving inversion-related benzene rings, forming slabs lying parallel to the bc plane {inter-centroid distance = 3.770 (2) Å].
