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 group of phosphinomethylmalic acid. It is a conjugate base of a 2-phosphinomethylmalic acid.
Assistant: This is a molecule that fits this description: O=C([O-])CC(O)(C[P+](=O)[O-])C(=O)[O-]
