Task: Please give me a SMILES based on the description below.
Description: The molecule is a triply-charged monocarboxylic acid anion obtained by deprotonation of the carboxy and phospho groups of 3-phosphonopyruvic acid. It derives from a pyruvate and a phosphonate(2-). It is a conjugate base of a 3-phosphonatopyruvate(2-).
Result: O=C([O-])C(=O)CP(=O)([O-])[O-]
