4'-(2,4-Dichlorophenyl)-1,1'-dimethyl-piperidine-3-spiro-3'-pyrrolidine-2'- spiro-3′-indoline-4,2″-dione

Abstract

In the title compound, C23H23Cl2N 3O2, the pyrroline ring adopts an envelope conformation and the piperidinone ring assumes a slightly twisted chair form. In the crystal, inversion dimers linked by pairs of N - H⋯O hydrogen bonds generate an R28 graph-set motif and a short Cl⋯Cl contact of 3.478 (1) Å occurs.
