In the nearly planar title compound (r.m.s.
deviation for the 24 summer beauty ornamental onion non-H atoms = 0.064 Å), C18H16ClN3O2, the conformation about the N=C bond is E.Supramolecular chains propagated by glide symmetry along [001] are found in gumball bere the crystal packing.
These are sustained by N—H.N hydrogen bonds with the quinoline N atom being the acceptor.The chains are connected into a three-dimensional architecture by π–π interactions involving all three aromatic rings [centroid–centroid distances = 3.
5650 (9)–3.6264 (9) Å].
