title: 1'-Methyl-4'-phenyldispiro-[indan-2,2'-pyrrolidine-3',2''-indan]-1,3,1''-trione.
abstract: The conformation of the title compound, C(27)H(21)NO(3), is stabilized by a weak intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. The pyrrolidine ring adopts a half-chair conformation. Both of the other five-membered rings are in envelope conformations. No significant inter-molecular hydrogen bonds are observed.
