Task: Please create a SMILES based on the text description below.
Description: The molecule is a dicarboxylic acid dianion that is obtained from dimethylmaleic acid by removal of a proton from each of the carboxylic acid groups. It derives from a maleate(2-). It is a conjugate base of a dimethylmaleic acid.
Result: C/C(C(=O)[O-])=C(\C)C(=O)[O-]
