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 BrBr 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 - stacking interactions [centroid-centroid distance 3.6811 (11) Å].
