Crystal structure of 7,7′-[(pyridin-2-yl)methylene]bis(5-chloroquinolin-8-ol)

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).
