Crystal structure and Hirshfeld surface analysis of 4'-(2-chloro-phen-yl)-1'-methyl-3''-phenyl-7'',8''-di-hydro-5''H-di-spiro-[indoline-3,2'-pyrrolidine-3',6''-iso-quinoline]-2,5''-dione.

In the title di-spiro compound, C32H26ClN3O2, the cyclo-hexa-none ring of the iso-quinoline unit has a distorted envelope conformation, with the methyl-ene C atom adjacent to the spiro C atom as the flap. The central 1-methyl-pyrrolidine ring has an envelope conformation with the N atom as the flap. The mean planes of the indolin-2-one ring system, the chloro-benzene ring and the iso-quinoline ring system are inclined to the mean plane of the central 1-methyl-pyrrolidine ring by 87.95 (11), 71.01 (12) and 88.81 (10)°, respectively. There are two short C-H⋯O intra-molecular contacts present. In the crystal, mol-ecules are linked via C-H⋯ O hydrogen bonds, forming chains along the a-axis direction. The NH H atom is involved in a weak N-H⋯O hydrogen bond with the same carbonyl O atom. There are no further significant inter-molecular contacts present. The largest contribution to the overall Hirshfeld surface of 52.3% is due to H-H contacts.
