Diethyl 6,9,17,20-tetrabromo-2,13-dioxohexacyclo[10.10.2.03,24.05,10.014,23.016,21]tetracosa-5,7,9,16,18,20-hexaene-23,24-dicarboxylate

Abstract

In the title molecule, C26H22Br4N4O6, 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.
