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....
