User: I'm searching for the SMILES of a molecule that can be described as:
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).
Assistant: This is a molecule that fits your description: [Fe].[cH-]1[cH-][cH-][cH-][cH-]1.c1cc[cH-]c1
