Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: C=CC1=C(C)c2cc3[n-]c(cc4nc(cc5[n-]c(cc1n2)c(C)c5CCC(=O)O)C(CCC(=O)[O-])=C4C)c(C)c3C=C.C=CC1=C(C)c2cc3[n-]c(cc4nc(cc5[n-]c(cc1n2)c(C)c5CCC(=O)[O-])C(CCC(=O)O)=C4C)c(C)c3C=C.[Fe].[Fe]
Constraint: Answer the question with full sentences.
Result: The molecule is a dimer of hematin in which an iron-oxygen bond links the central iron of one hematin to the oxygen of one of the carboxylates of the adjacent hematin.
