【 摘 要 】

In the title dispiro compound, C32H26ClN3O2, the cyclohexanone ring of the isoquinoline unit has a distorted envelope conformation, with the methylene C atom adjacent to the spiro C atom as the flap. The central 1-methylpyrrolidine ring has an envelope conformation with the N atom as the flap. The mean planes of the indolin-2-one ring system, the chlorobenzene ring and the isoquinoline ring system are inclined to the mean plane of the central 1-methylpyrrolidine ring by 87.95 (11), 71.01 (12) and 88.81 (10)°, respectively. There are two short C—H...O intramolecular contacts present. In the crystal, molecules 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 intermolecular contacts present. The largest contribution to the overall Hirshfeld surface of 52.3% is due to H—H contacts.
