In the title compound, C(20)H(18)Br(2)N(4)O(8), the inter-planar angle of the pyrimidine rings is 75.1 (2)°. The central benzene ring is inclined at inter-planar angles of 66.5 (2) and 71.9 (2)° with respect to the two pyrimidine rings. In the crystal structure, adjacent mol-ecules are connected into two-mol-ecule-thick arrays parallel to the bc plane via short Br⋯Br [3.5328 (12) Å] and Br⋯O [3.206 (3) and 3.301 (4) Å] inter-actions. A weak inter-molecular π-π aromatic stacking inter-action [cen ...[more]
