User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a zwitterion that is derived from 3,4-bis(7-chloroindol-3-yl)-2,5-diiminohexanedioic acid by deprotonation of both carboxylic acid groups and protonation of both amino groups; major species at pH 7.3. It is a tautomer of a 3,4-bis(7-chloroindol-3-yl)-2,5-diiminohexanedioic acid.
Assistant: This is a molecule that fits this description: N=C(C(=O)O)C(c1c[nH]c2c(Cl)cccc12)C(C(=N)C(=O)O)c1c[nH]c2c(Cl)cccc12
