Abstract
In the title compound, C19H13N3O, the dihedral angle between the two quinoline systems is 11.54 (3)°. The molecular conformation is stabilized by intramolecular N—H⋯N and C—H⋯O hydrogen bonds, with N—H⋯N being bifurcated towards the two N atoms of the two quinoline rings. In the crystal, there are weak intermolecular π–π interactions present involving the quinoline rings [centroid–centroid distance 3.7351 (14) Å].
