Abstract

In the title benzyl-ideneaniline Schiff base, C₁₈H₂₂N₂O, 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.

Keywords: Hirshfeld surface analysis; Schiff base; benzylideneaniline; crystal structure; energy framework.
