description The title Schiff base compound, C(20)H(18)N(4), lies across a crystallographic inversion centre and adopts E configurations with respect to the C=N bonds. The asymmetric unit of the compound is composed of one half-mol­ecule. The imino group is coplanar with the benzene ring. Within the mol­ecule, the planar units are parallel but extend in opposite directions from the methyl­ene bridge. In the crystal structure, neighbouring mol­ecules are linked together by weak inter­molecular C—H⋯N hydrogen bonds involving the cyano N atoms. These form ten-membered rings, generating R (2) (2)(10) ring motifs, and link the mol­ecules along the c axis.
