( E )- N , N -Diethyl-4-{[(4-meth-oxy-phen-yl)imino]-meth-yl}aniline: crystal structure, Hirshfeld surface analysis and energy framework.

In the title benzyl-ideneaniline Schiff base, C 18 H 22 N 2 O, the aromatic rings are inclined to each other by 46.01 (6)°, while the C ar -N= C-C ar torsion angle is 176.9 (1)°. In the crystal, the only identifiable directional inter-action is a weak C-H⋯π hydrogen bond, which generates inversion dimers that stack along the a -axis direction.
