User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is the tetracarboxylic acid anion formed by deprotonation of three of the four carboxy groups in ethylenediaminetetraacetic acid (EDTA). It is a conjugate base of an EDTA(2-).
Assistant: This is a molecule that fits your description: O=C([O-])CN(CCN(CC(=O)[O-])CC(=O)O)CC(=O)[O-]
