4,4'-[Butane-1,4-diylbis(nitrilo-methyl-idyne)]dibenzonitrile.

ABSTRACT: 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-mol-ecule. The imino group is coplanar with the benzene ring. Within the mol-ecule, the planar units are parallel but extend in opposite directions from the methyl-ene bridge. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular 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 mol-ecules along the c axis.
