title: Crystal structure of 7-{[bis-(pyridin-2-ylmeth-yl)amino]-meth-yl}-5-chloro-quinolin-8-ol.
abstract: In the title compound, C22H19ClN4O, the quinolinol moiety is almost planar [r.m.s. deviation = 0.012 Å]. There is an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy group and a pyridine N atom forming an S(9) ring motif. The dihedral angles between the planes of the quinolinol moiety and the pyridine rings are 44.15 (9) and 36.85 (9)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds forming inversion dimers with an R 4 (4)(10) ring motif. The dimers are linked by C-H⋯N hydrogen bonds, forming ribbons along [01-1]. The ribbons are linked by C-H⋯π and π-π inter-actions [inter-centroid distance = 3.7109 (11) Å], forming layers parallel to (01-1).
