User: I want to come up with a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule can be described as:
The molecule is a cyclic tetrapyrrole anion arising from deprotonation of the four carboxy groups of ferroheme d1; major species at pH 7.3. It is a cyclic tetrapyrrole anion and a tetracarboxylic acid anion. It is a conjugate base of a ferroheme d1.
Assistant: Got it, here you go, this SMILES fits your description: Cc1c(/C=C/C(=O)[O-])c2cc3[n-]c(cc4nc(cc5nc(cc1[n-]2)[C@@](C)(CC(=O)[O-])C5=O)[C@@](C)(CC(=O)[O-])C4=O)c(C)c3CCC(=O)[O-].[Fe]
