Experimental

R factor = 0.035; wR factor = 0.097; data-to-parameter ratio = 15.0. 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), respec-tively, with the cyclopentane ring. The F atom deviates by 0.0238 (2) A ̊ from the benzene ring to which it is attached. In the crystal, molecules are linked by a pair of C—H O hydrogen bonds, forming inversion dimers.
