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. |
