Task: Please generate a molecule SMILES based on the text description.
Description: The molecule is a dicarboxylic acid dianion resulting from the removal of a proton from both of the carboxy groups of heme d cis-diol. It has a role as a cofactor. It is a conjugate base of a heme d cis-diol.
Result: C=CC1=C(C)c2cc3[n-]c(cc4nc(cc5[n-]c(cc1n2)c(C)c5C=C)[C@](C)(O)[C@@]4(O)CCC(=O)[O-])c(CCC(=O)[O-])c3C.[Fe]
