In the title compound, C7H6FNO2, the molecule is almost planar (r.m.s. deviation for the non-H atoms = 0.015 Å) and an intramolecular N—HO hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O—HO hydrogen bonds generate R22(8) loops. Weak N—HF hydrogen bonds, short FF contacts [2.763 (2) Å] and aromatic π–π stacking interactions [centroid–centroid separation = 3.5570 (11) Å] are also observed in the crystal structure.

In the title compound, [Fe(C5H5)(C32H24N3OS)], both the thiazolidine ring and the pyrrolidine ring adopt an envelope conformation, with the S atom and the phenyl-bearing C atom, respectively, as the flaps. The thiazolidine ring mean plane makes a dihedral angle of 59.08 (11)° with the pyrrolidine ring mean plane, which in turn makes a dihedral angle of 83.40 (10)° with the cyclopentane ring, indicating that the latter two rings are almost orthogonal to one another. In the crystal, a pair of C—HO hydrogen bonds link the molecules forming inversion dimers. The dimers are linked via π–π interactions [centroid–centroid distance = 3.7764 (10) Å] involving the quinoxaline moieties forming chains propagating along [1-10].

In the title compound, [Fe(C5H5)(C32H23FN3OS)], both the thiazolidine ring and the pyrrolidine ring adopt a twist conformation on the N—C(H) bridging bond. Their mean planes are inclined to one another by 10.05 (10)°, and they make dihedral angles of 82.09 (10) and 89.67 (11)°, respectively, with the cyclopentane ring. The F atom deviates by −0.0238 (2) Å from the benzene ring to which it is attached. In the crystal, molecules are linked by a pair of C—HO hydrogen bonds, forming inversion dimers.

In the title compound, [Fe(C5H5)(C33H25BrN3O)], the fused four-ring system, 11H-indeno[1,2-b]quinoxaline is essentially planar, with a maximum deviation of 0.087 (3) Å from the least-squares plane of the attached benzene ring. The pyrrolidine rings adopt envelope conformation and make a dihedral angle of 51.76 (19)° with each other. The cyclopentadiene rings of the ferrocenyl moiety have an eclipsed conformation. The Br atom deviates by 0.0190 (9) Å from the attached benzene ring. The molecular structure features an intramolecular C—HN interaction, which generates an S(8) ring motif. The crystal packing features C—HO interactions, which generate R22(18) centrosymmetric dimers, as well as C—Hπ interactions.
