Abstract: The title compound, C30H28ClN3O2, features two spiro links, one connecting the piperidine and pyrrolidine rings, and the other connecting the pyrrolidine ring and indole residue. The configuration about the ethene bond is E. The piperidine ring adopts a half-chair conformation where the C atom connected to the spiro-C atom lies 0.713 (3) Å out of the plane of the remaining five atoms (r.m.s. deviation = 0.086 Å). The pyrrolidine ring has an envelope conformation with the flap atom being the methyl­ene C atom. Centrosymmetric eight-membered {...HNCO}2 amide synthons feature in the crystal packing. These are consolidated into a three-dimensional architecture by phen­yl-pyrrolidine C-H...N and chloro­benzene-pyrrolidine-bound phenyl C-H...[pi] inter­actions.
