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 0.076â (1) and 0.029â (1)â Å in the two rings] and are oriented at a dihedral angle of 72.7â (1)°. The crystal structure is stabilized by C-Hâ¯O, N-Hâ¯O, N-Hâ¯N and C-Hâ¯π inter-actions.

ABSTRACT
In the title compound, C(23)H(18)N(2)O(4)·H(2)O, the two oxindole rings subtend a dihedral angle of 54.29â (5)°. The crystal structure is stabilized by intermolecular N-Hâ¯O, O-Hâ¯O and C-Hâ¯π inter-actions.
