User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a dicarboxylic acid dianion obtained by deprotonation of the carboxy groups of 4-nitro-6-oxohepta-2,4-dienedioic acid; major species at pH 7.3. It is a conjugate base of a 4-nitro-6-oxohepta-2,4-dienedioic acid.
Assistant: This is a molecule that fits this description: O=C([O-])/C=C/C(=C\C(=O)C(=O)[O-])[N+](=O)[O-]
