The structure of the molecule, C15H14N2O3, consists of essentially pla
nar and parallel nitroaniline and benzaldehyde fragments [dihedral ang
le 2.7 (4)-degrees], linked through an ethylene bridge between the ani
line N atom and an ortho C atom of the benzaldehyde fragment. The alde
hyde and nitro substituents are essentially coplanar with their respec
tive rings. Intramolecular hydrogen bonding occurs between the ammo an
d nitro groups; there are no significant intermolecular interactions.
