Task: Please create a description for a molecule.
Molecule SMILES: [Fe].[cH-]1[cH-][cH-][cH-][cH-]1.c1cc[cH-]c1
Constraint: Answer the question with complete sentences.
Result: The molecule is a bis(eta(5)-cyclopentadienyl)metal(II) having Fe(II) as the metal(II) species. The parent of the class of ferrocenes. It has a role as a fuel additive. It is a member of ferrocenes and a bis(eta(5)-cyclopentadienyl)metal(II).
