چکیده
The asymmetric unit of the title compound, [Fe(C(5)H(5))(C(7)H(8)N(3)S)], consists of two crystallographically independent mol-ecules, A and B. The cyclo-penta-dienyl (Cp) rings in both mol-ecules 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 mol-ecule A, whereas it is twisted away in mol-ecule B. In the crystal structure, inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into two-dimensional planes parallel to the ab plane. The structure is further consolidated by C-H⋯π inter-actions.
