User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a monovalent inorganic anion obtained by deprotonation of one of the two OH groups in diphosphoniic acid. It is a phosphorus oxoanion and a monovalent inorganic anion. It is a conjugate base of a diphosphonic acid. It is a conjugate acid of a diphosphonate(2-).
Assistant: This is a molecule that fits this description: O=[P+]([O-])O[P+](=O)O
