Thermodynamic study of lanthanide(III) complexes with bifunctional monophosphinic acid analogues of H4dota and comparative kinetic study of yttrium(III) complexes

Abstract

Thermodynamic stabilities of the Ln(III) complexes with monophosphinic analogues of H(4)dota bearing propionate or 4-aminobenzyl group were determined by potentiometry. Formation and dissociation kinetics of the Y(III) complexes were studied.
