N,N′-Bis(4-bromobenzylidene)butane-1,4-diamine

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) 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 interactions [centroid–centroid distance 3.6811 (11) Å].
