چکیده
The mol-ecule of the title Schiff base compound, C(18)H(18)Br(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the C=N bond. In the crystal structure, mol-ecules are linked into chains along [201] through inter-molecular Br⋯Br inter-actions [3.3747 (3) Å], which are significantly shorter than the sum of the van der Waals radii for Br atoms (3.70 Å). The crystal structure is further stabilized by π-π stacking inter-actions [centroid-centroid distance 3.6811 (11) Å].

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.
