✦ Synopsis

The molecule of the title compound, C~22~H~30~N~4~, lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bond. The molecular structure has a staggered conformation, with the two benzene rings parallel to each other. The dihedral angle between the benzylidene and butane groups is 77.77 (7)°. In the crystal structure, molecules are arranged into columns along the a axis by C—H...π interactions.
