N,N′-Bis(4-bromobenzylidene)butane-1,4-diamineDOI: 10.1107/s1600536808028122 Abstract: The molecule of the title Schiff base compound, C18H18Br2N2, lies across a crystallographic inversion centre and adopts an E configuration with respect to the C=N bond. In the crystal structure, molecules are linked into chains along [201] through intermolecular Br...Br interactions [3.3747 (3) ], which are significantly shorter than the sum of the van der Waals radii for Br atoms (3.70 ). The crystal structure is further stabilized by π–π stacking interactions [centroid–centroid distance 3.6811 (11) ].
