Acidic Complexones Bearing Donor-enhancing Pyridine Anchour Groups

The synthesis, complex stability and -selectivity for alkaline earth metal ions 2,6-pyridinebis(methylamine)-N,N,N',N'-tetraacetic acids (3a) and their donor-enforced analogues 3b,c are described.The acid dissociation constants and the stability constants of the metal complexes have been measured potentiometrically at 25 deg C in water of constant ionic strength (μ = 0.1).The stability order is Ca > Mg > Sr > Ba which is analogous to the selectivity of EDTA and comparable aliphatic complexones.The magnitudes of the stability constants of 3a are comparable to those of EDTA, while the donor-enforced analogues 3b,c form less stable complexes with alkaline earth metal ions.
