User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a C4-dicarboxylate resuting from deprotonation of both carboxy groups of dihydroxyfumaric acid. It derives from a fumarate(2-). It is a conjugate base of a dihydroxyfumaric acid.
Assistant: This is a molecule that fits your description: O=C(O)/C([O-])=C(\[O-])C(=O)O
