Crystal Structure of 1-N-Methyl-spiro-[2-3′]oxindole-spiro[3-2″]-indane-1″,3″-dione-4-(p-methyl phenyl)pyrrolidine

1-N-Methyl-spiro-[2-3′]oxindole-spiro[3-2″]-indane-1″,3″-dione-4-(p-methylphenyl) pyrrolidine was used for an X-ray crystallographic analysis to confirm our project on spiro pyrrolidine compounds. The title compound crystallizes in the triclinic space group, P1. In the crystal structure, the pyrrolidine ring adopts a half-chair conformation. In the crystal packing, symmetry-related molecules are linked by N-H…O and C-H…O dimer interactions. Apart from these interactions, the molecular packing is further stabilized by C-H…π and π…π interactions.
