The structures of dioxotetramine ligands are similar to those of the oligopeptides. They are able to form stable complexes with transition metal ions. The two amide moieties in these compounds lose hydrogen ions during coordination with divalent metal ions; therefore they are able to stabilize high oxidation states of metal ions in aqueous solution [1]. The dioxotetraamine ligands have attracted people’s interest due to special coordination properties and practicality [2, 3].
