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 two of the four carboxy groups in ethylenediaminetetraacetic acid (EDTA). It is a conjugate base of an ethylenediaminetetraacetic acid. It is a conjugate acid of an EDTA(3-).
Assistant: This is a molecule that fits this description: O=C([O-])C[NH+](CC[NH+](CC(=O)[O-])CC(=O)[O-])CC(=O)[O-]
