Summary The acid dissociation constants of nicotianamine (1) (pK1=6.97, pK2=9.13, pK3=9.75; 0.1 M KClO4, 25°C) and the stability constants for its 1∶1 complexes with bivalent metal ions (log KCu=18.6, log KNi=16.1, log KCo=14.8, log KZn=14.7, log KFe=12.1, log KMn=8.8, log KMg≈4.5; 0.1 M KClO4, 25°C) were determined using potentiometric titrations in aqueous solution. Fe(III)-nicotianamine complexes were not detected under the same experimental conditions.
