Task: Please create a text description for a molecule.
Molecule SMILES: O=C([O-])/C=C/C(=C\C(=O)C(=O)[O-])[N+](=O)[O-]
Constraint: Answer the question with full sentences.
Result: 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.
