5,7-Di­bromo-4′-(4-bromo­benzoyl)-1′-methyl-1H-indole-3-spiro-2′-pyrrolidine-3′-spiro-3′′-1H-indole-2,2′′(3H,3′′H)-dione methanol solvate

The pyrrolidine ring of the title compound, C₂₆H₁₈Br₃N₃O₃·CH₄O, adopts an envelope conformation. The molecular structure is stabilized by C—H⋯O interactions and the packing is stabilized by N—H⋯O and O—H⋯N intermolecular interactions, which also include the methanol solvent molecules.
