User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a dicarboxylic acid dianion obtained via deprotonation of both carboxy groups of 2-oxo-2H-pyran-4,6-dicarboxylic acid; major species at pH 7.3. It is a conjugate base of a 2-oxo-2H-pyran-4,6-dicarboxylic acid.
Assistant: This is a molecule that fits your description: O=C([O-])c1cc(C(=O)[O-])oc(=O)c1
