Crystal structure of (2-hy-droxy-5-methyl-phen-yl)(3-methyl-1-phenyl-1H-pyrazolo-[3,4-b]pyridin-5-yl)methanone.
In the title compound, C21H17N3O2, the 2-hy-droxy-5-methyl-phenyl ring and the phenyl ring are inclined to the mean plane of the pyrazolo-pyridine moiety (r.m.s. deviation = 0.013 Å) by 52.89 (9) and 19.63 (8)°, respectively, and to each other by 42.83 (11)°. In the mol-ecule, there are intra-molecular O-H⋯O and C-H⋯N hydrogen bonds, both enclosing an S(6) ring motif. In the crystal, mol-ecules stack along the c-axis direction, forming columns within which there are a number of π-π inter-actions [the inter-centroid distances vary from 3.5278 (10) to 3.8625 (10) Å]. The columns are linked by C-H⋯π inter-actions, forming slabs parallel to (100).
