Abstract
In the title compound, C22H14ClN3O2, the indole unit is essentially coplanar, with a maximum deviation of 0.035 Å for the C atom bearing the methyl group. The central pyridine ring is inclined to the indole ring system by 43.7 (1)°. The dihedral angle between the phenyl ring and the indole ring system is 15.7 (2)°, while that between the phenyl ring and the central pyridine ring is 46.3 (1)°. The molecular structure is stabilized by an intramolecular O—H⋯O hydrogen bonding, forming an S(6) ring motif. In the crystal, molecules are linked via pairs of N—H⋯N hydrogen bonds, forming inversion dimers with an R 2 2(16) ring motif. The crystal structure also features C—H⋯π and π–π interactions [centroid–centroid separation = 3.688 (1) Å].
