Task: Please give me a molecule SMILES based on the text description below.
Description: The molecule is a dicarboxylic acid anion obtained by deprotonation of the carboxy and phosphino groups of 2-(phosphinomethylidene)butanedioic acid; major species at pH 7.3. It is a conjugate base of a 2-(phosphinomethylidene)succinic acid.
Result: O=C([O-])C/C(=C/[P+](=O)[O-])C(=O)[O-]
