User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is the trianion resulting from the removal of three protons from phosphonoformic acid. It is a conjugate base of a phosphonoformic acid and a phosphonoformate(2-).
Assistant: This is a molecule that fits your description: O=C([O-])P(=O)([O-])[O-]
