User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a tricarboxylic acid trianion resulting from deprotonation of the three carboxy groups of (2Z,4E)-4-carboxy-2-hydroxyhexa-2,4-dienedioic acid. It is a conjugate base of a (2Z,4E)-4-carboxy-2-hydroxyhexa-2,4-dienedioic acid.
Assistant: This is a molecule that fits your description: O=C(O)/C=C(\C=C(/[O-])C(=O)[O-])C(=O)[O-]
