1-Methyl-4′-(3-nitro­phenyl)-1H-indole-3-spiro-2′-pyrrolidine-3′-spiro-2′′-indan-2,1′′,3′′-trione

The pyrrolidine ring of the title compound, C26H19N3O5, adopts an envelope conformation. The molecular structure is stabilized by C—H⋯O interactions and the packing of the mol­ecules is stabilized by an N—H⋯O hydrogen bond and C—H⋯O intermolecular interactions. A dimer is formed between symmetry-related mol­ecules through N—H⋯O hydrogen bonds.
