چکیده
The asymmetric unit of the title compound, C(18)H(16)F(4)N(2), comprises two half crystallographically independent potentially bidentate Schiff base ligands, with an inversion centre located at the mid-point of the central C-C bond. The crystal packing is stabilized by inter-molecular C-H⋯F and π-π inter-actions [centroid-centroid distance = 3.8283 (11) Å].

متن کاملN,N′-Bis(3,4-dimethoxybenzylidene)butane-1,4-diamine
The title Schiff base compound, C(22)H(28)N(2)O(4), was synthesized by the reaction of 3,4-dimethoxy-benzaldehyde and 1,4-diamino-butane in methanol. The mol-ecule is located on a center of inversion with one half-mol-ecule in the asymmetric unit. Both C=N double bonds are in a trans configuration. Inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
