User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is trianion of 1-carboxyvinyl carboxyphosphonate arising from deprotonation of the carboxy and phosphonate groups; major species at pH 7.3. It is a dicarboxylic acid dianion and an organophosphonate oxoanion. It is a conjugate base of a 1-carboxyvinyl carboxyphosphonate.
Assistant: This is a molecule that fits this description: C=C(OP(=O)([O-])C(=O)[O-])C(=O)[O-]
