title: 4-{Eth-yl[(E)-4-(4-pyridylvin-yl)phenyl]-amino}benzaldehyde.
abstract: In the title mol-ecule, C(22)H(20)N(2)O, the central aromatic ring forms dihedral angles of 45.30 (2) and 69.43 (2)°, respectively, with the outer pyridine and benzene rings. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into layers parallel to the ab plane.
