Abstract :
In the title compound, C24H15Cl2N3O2, one quinoline ring system is essentially planar and the other is slightly bent. An intramolecular O—H⋯N hydrogen bond involving the hydroxy group and a pyridine N atom forms an S(5) ring motif. In the crystal, two molecules are associated into an inversion dimer with two R22(7) ring motifs through intermolecular O—H⋯N and O—H⋯O hydrogen bonds. The dimers are further linked by an intermolecular C—H⋯O hydrogen bond and four C—H⋯π interactions, forming a two-dimensional network parallel to (001).
