Lanthanide(III) complexes of some natural siderophores: A thermodynamic, kinetic and relaxometric study

The given manuscript reports on the complexation properties of desferrioxamine B and desferricoprogen towards lanthanide(III) ions in solution studied by means of pH-potentiometry, UV-vis spectrophotometry, 1H- and 17O-relaxometry. The natural hydroxamates studied form mostly mononuclear complexes with Ln(III) ions of relatively low stability, which are kinetically labile.
