User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a dicarboxylic acid anion obtained by deprotonation of the carboxy and phosphino groups of phosphinomethylisomalic acid; major species at pH 7.3. It is a conjugate base of a phosphinomethylisomalic acid.
Assistant: This is a molecule that fits your description: O=C([O-])C(O)C(C[P+](=O)[O-])C(=O)[O-]
