(E)-N′-(3-Nitrobenzylidene)-4-(8-quinolyloxy)butanohydrazide

Abstract

In the title Schiff base compound, C20H18N4O4, 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 inter­molecular N—H⋯N hydrogen bonds link the mol­ecules into centrosymmetric R 2 2(20) dimers, which are aggregated via π–π inter­actions into sheets [quinoline–benzene ring centroid–centroid separation = 3.572 (2)–3.773 (3) Å].
