title: (E)-N'-(3-Nitro-benzyl-idene)-4-(8-quinol-yloxy)butano-hydrazide.
abstract: In the title Schiff base compound, C(20)H(18)N(4)O(4), the conformation along the bond sequence linking the benzene and quinoline rings is trans-(+)gauche-trans-trans-(+)gauche-trans-trans. The dihedral angle between the aromatic ring systems is 80.3 (6)°. In the crystal, a pair of inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(20) dimers, which are aggregated via π-π inter-actions into sheets [quinoline-benzene ring centroid-centroid separation = 3.572 (2)-3.773 (3) Å].
