User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a dicarboxylic acid that is succinic acid substituted at position 2 by a phosphinomethylidene group. It is a member of phosphinic acids and a dicarboxylic acid. It derives from a succinic acid. It is a conjugate acid of a 2-(phosphinatomethylidene)succinate(3-).
Assistant: This is a molecule that fits your description: O=C(O)C/C(=C/[P+](=O)O)C(=O)O
