Diethyl 6,9,17,20-tetra­bromo-2,13-di­oxo­hexa­cyclo­[10.10.2.0(3,24).0(5,10).0(14,23).0(16,21)]tetra­cosa-5,7,9,16,18,20-hexa­ene-23,24-dicarboxyl­ate

In the title mol­ecule, C(26)H(22)Br(4)N(4)O(6), the dihedral angle between the aromatic rings is 30.0 (1)°. One ethyl fragment is disordered between two positions in a 1:1 ratio. The crystal packing exhibits weak inter­molecular C—H⋯O hydrogen bonds and short Br⋯O contacts of 3.349 (6) Å....
