摘要
In the title molecule, C26H22Br4N4O6, the dihedral angle between the aromatic rings is 30.0 (1)degrees. One ethyl fragment is disordered between two positions in a 1:1 ratio. The crystal packing exhibits weak intermolecular C-H center dot center dot center dot O hydrogen bonds and short Br center dot center dot center dot O contacts of 3.349 (6) angstrom.
