In the title compound, [Fe(C5H5)(C14H10NO3)], the cyclopentadienyl rings are in an eclipsed conformation and the pyran ring adopts a half-chair conformation. The mean plane of the pyran ring makes dihedral angles of 79.33 (1) and 80.73 (1)°, respectively, with the substituted and unsubstituted cyclopentadienyl rings. In the crystal, pairs of C—HO hydrogen bonds link the molecules into inversion dimers with R22(16) motifs.

In the title compound, C29H23N3O4, the 2-methylpyrrolidine ring adopts a twist conformation on the N—C bond involving the spiro C atom, while the hydropyran ring adopts an envelope conformation with the methine C atom bonded to the O atom as the flap. The mean plane of the indoline-2-one ring system is almost perpendicular to the mean plane of the pyrrolidine ring, making a dihedral angle of 89.73 (8)°. The latter ring makes dihedral angles of 47.80 (8) with the naphthalene ring system and 32.38 (8)° with the hydropyran ring mean plane. There is an intramolecular C-HO hydrogen bond involving the indoline-2-one O atom. In the crystal, adjacent molecules are linked via N—HO hydrogen bonds, forming chains propagating along [100]. The chains are linked via weak C—HO hydrogen bonds, forming two-dimensional networks, lying parallel to (101), and consolidated by C—Hπ interactions.

In the title compound, C29H27N3O5, the hydropyran ring adopts an envelope conformation with the methine C atom bearing the para-methoxybenzene ring as the flap. The central pyrrolidine ring has a twist conformation on the N—C bond involving the spiro C atom. The piperidine ring adopts a chair conformation. An intramolecular C—HO contact closes an S(7) ring. In the crystal, inversion dimers linked by C—HO interactions generate R22(18) loops and N—HO hydrogen bonds connect the dimers into [100] chains.
