| description | The asymmetric unit of the title Schiff base compound, C20H18N4, contains one half-molecule, lying across a crystallographic inversion centre and adopting an E configuration with respect to the C=N bonds. The imino group is coplanar with the benzene ring with a maximun deviation of 0.096 (1) Å for the N atom. 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, forming R22(10) ring motifs. |
