Complex formation of iron(II) with diglycolic and iminodiacetic acids

Reversible Coordinative Bonds in Molecular Recognition

“…Since then it has been widely used as a chelating ligand for various metal ions, e.g. Cu(II), Ni(II), Zn(II), Co(III), Fe(III), Al(III), and Cr(III). − Table summarizes the metal ion binding constants of some typical complexes. Complexes with ligand to transition metal ion stoichiometries of 1:1 and 2:1 are typical.…”
