User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an oxo dicarboxylic acid that is 6-oxohepta-2,4-dienedioic acid substituted at position 4 by a nitro group. It is a C-nitro compound, an oxo dicarboxylic acid and a ketone. It is a conjugate acid of a 4-nitro-6-oxohepta-2,4-dienedioate.
Assistant: This is a molecule that fits this description: O=C(O)/C=C/C(=C\C(=O)C(=O)O)[N+](=O)[O-]
