User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a C4-dicarboxylate resulting from the removal of a proton from both carboxylic acid groups of enol-oxaloacetic acid. It is a C4-dicarboxylate and a dicarboxylic acid dianion. It derives from a butenedioate. It is a conjugate acid of an enol-oxaloacetic acid.
Assistant: This is a molecule that fits your description: O=C(O)/C=C(\[O-])C(=O)[O-]
