A second monoclinic polymorph of 4,4′-[butane-1,4-diylbis(nitrilomethylidyne)]dibenzonitrile
The asymmetric unit of the title Schiff base compound, C(20)H(18)N(4), 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) ...
