The asymmetric unit of the title compound, [Fe(C5H5)(C7H8N3S)], consists of two crystallographically independent molecules, A and B. The cyclopentadienyl (Cp) rings in both molecules adopt an eclipsed conformation and are parallel to each other, forming dihedral angles of 2.5 (3) and 1.1 (3)°, respectively. The mean plane of the semicarbazone group is coplanar with the attached Cp ring in molecule A, whereas it is twisted away in molecule B. In the crystal structure, intermolecular N—H...S hydrogen bonds link the molecules into two-dimensional planes parallel to the ab plane. The structure is further consolidated by C—H...π interactions.
