User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a dicarboxylic acid dianion that is obtained by removal of a proton from both of the carboxylic acid groups of citramalic acid. It has a role as a human metabolite and a plant metabolite. It derives from a butenedioate. It is a conjugate base of a citramalic acid.
Assistant: This is a molecule that fits your description: CC(O)(CC(=O)[O-])C(=O)[O-]
