In the molecule of the title compound, C21H20Br 2N2O4, the 4,10-dibromo-2,8-diethyl ester analogue of Tröger's base, the diazocine bridge imparts a twist such that the two aryl rings are offset with respect to one another. A twofold rotation axis passes through the bridgehead C atom. The asymmetric unit contains only one-half molecule and the dihedral angle between the two symmetry-related benzene rings is 98.24 (4)°.
