User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a dicarboxylic acid dianion resulting from the deprotonation of both of the carboxy groups of 4,4'-disulfanyldibutanoic acid. It is a conjugate base of a 4,4'-disulfanyldibutanoic acid.
Assistant: This is a molecule that fits your description: O=C([O-])CCCSSCCCC(=O)[O-]
