User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an organophosphonate oxoanion that is the conjugate base of 2-hydroxyethylphosphonic acid, arising from deprotonation of one of the two phosphonate OH groups; major species at pH 7.3. It is a conjugate base of a 2-hydroxyethylphosphonic acid.
Assistant: This is a molecule that fits your description: O=P([O-])(O)CCO
