Abstract
In the title compound, C34H25N3O4·0.5CH2Cl2, which crystallized as a dichloromethane hemisolvate, the central 1-methylpyrrolidine ring adopts an envelope conformation with the N atom as the flap. The cyclopentane ring adopts a twist conformation on the CH—CH2bond and the cyclohexane ring has an envelope conformation with the CH2atom as the flap. The pyrrolidine ring mean plane makes dihedral angles of 40.09 (11), 69.21 (10) and 80.88 (8)° with the mean planes of the cyclopentane, cyclohexane and acenaphthylene rings, respectively. The 3-nitrobenzene ring is inclined to the acenaphthylene and quinoline ring systems by 69.32 (8) and 82.07 (7)°, respectively. There is an intramolecular O—H...N hydrogen bond present forming anS(5) ring motif. In the crystal, molecules are linked by C—H...O hydrogen bonds, forming sheets lying parallel to theabplane, which encloseR22(18),R22(14),R22(12) andR22(16) ring motifs.

Abstract
In the title solvate, C35H25ClN2O3·0.5CH3OH, the conformation of the central 1-methylpyrrolidine ring is best described as an envelope with the N atom as the flap. The cyclopentane ring adopts a twist conformation on the CH—CH2bond and the cyclohexane ring has an envelope conformation with the CH2atom as the flap. The pyrrolidine ring makes dihedral angles of 40.87 (12), 67.89 (11), 81.86 (9) and 70.86 (12)° with the mean planes of the cyclopentane, cyclohexane, acenaphthylene and chlorobenzene rings, respectively. The quinoline ring system is inclined to the naphthalene ring system by 54.14 (6)°. There is a short O—H...N contact in the molecule making anS(5) ring motif. In the crystal, there is a disordered and partially occupied ethan-1,2-diol solvent molecule present, located about an inversion centre, which links the title moleculesviaO—H...O and C—H...O hydrogen bonds, forming chains propagating along thea-axis direction.

Abstract
In the title compound, C30H23N3O4, the central 1-methylpyrrolidine ring adopts a twist conformation on the N—CH2 bond. The pyrrolidin-2-one ring of the indolin-2-one ring system also has a twist conformation on the C—C bond involving the spiro C atom and the carbonyl C atom. The five-membered ring of the indene-1,3-dione moiety has an envelope conformation with the spiro C atom as the flap. The quinoline ring system adopts an almost planar conformation (r.m.s. deviation = 0.04 Å). The mean planes of the indolin-2-one ring system, the indene-1,3-dione ring system and the the quinoline ring system are inclined to the mean plane of the central 1-methylpyrrolidine ring by 77.97 (7), 86.98 (7) and 46.58 (6)°, respectively. In the crystal, molecules are linked via N—H⋯N hydrogen bonds, forming chains along the b axis. The chains are linked via a number of C—H⋯O hydrogen bonds, and C—H⋯π and π–π interactions [inter-centroid distance = 3.7404 (9) Å], forming a three-dimensional network.

Abstract
In the title compound, C34H25ClN2O2, the fused pyrrolidine ring adopts an envelope conformation with the N atom as the flap. The two adjacent cyclo-pentane rings also adopt envelope conformations. The mean plane of the pyrrolidine ring makes dihedral angles of 40.53 (10) and 80.23 (10)° with the mean planes of the cyclo-pentane rings. The dihedral angle between the mean planes of the cyclo-pentane rings is 46.71 (9)°. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal, mol-ecules are linked by C-H⋯O, C-H⋯N and C-H⋯π inter-actions, forming a layer parallel to (10-2).
