The 150 K structure of the title compound, C20H28Br2N8, has been shown to exhibit liquid-crystal alignment in the gross array, enhanced by the presence of intermolecular Br…Br interactions. The asymmetric unit consists of one-half of a molecule, the remainder being generated via a crystallographic inversion centre located at the centre of the benzene ring.
