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 - interactions [centroid-centroid distance = 3.7764 (10) Å] involving the quinoxaline moieties forming chains propagating along [1-10].
