The molecule of the title Schiff base compound, C18H14N4, lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine (C=N) bonds. The imino groups are coplanar with the aromatic rings with a maximum deviation of 0.1574 (12) Å for the N atom. Within the molecule, the planar units are parallel, but extend in opposite directions from the dimethylene bridge. In the crystal structure, pairs of intermolecular C—H⋯N hydrogen bonds link neighbouring molecules into centrosymmetric dimers with R 2 2(10) ring motifs. An interesting feature of the crystal structure is the short intermolecular C⋯C interaction with a distance of 3.3821 (13) Å, which is shorter than the sum of the van der Waals radius of a carbon atom.
