1'-Methyl-2,2''-dioxoindoline-3-spiro-2'-pyrrolidine-3'-spiro-3''-indoline-4',4'-di-carbonitrile.


ABSTRACT: In the title compound, C(21)H(15)N(5)O(2), the pyrrolidine ring adopts a twist conformation. Both the oxindole rings are planar [maximum deviations of 0.076 (1) and 0.029 (1) Å in the two rings] and are oriented at a dihedral angle of 72.7 (1)°. The crystal structure is stabilized by C-H⋯O, N-H⋯O, N-H⋯N and C-H⋯π inter-actions.
