5,5''-Dibromo-1,1''-bis-(prop-2-en-1-yl)-1,1'',2,2''-tetra-hydro-dispiro-[indole-3,7'-[6,9]diaza-tricyclo-[7.3.0.0(2,6)]dodecane-8',3''-indole]-2,2''-dione.

In the mol-ecule of the title compound, C(30)H(30)Br(2)N(4)O(2), the piperazine ring adopts a chair conformation. The pyrrolidine rings that are fused to the piperazine ring adopt envelope conformations (in which the N atom represents the flap). The indoline fused-ring systems are nearly planar (r.m.s. deviations = 0.009 and 0.019 Å); the two fused rings are aligned at 60.63 (6)°.
