N-(Quinolin-8-yl)quinoline-2-carboxamide [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 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.
