Preparation, characterization and determination of acid dissociation and stability constants of some acid divalent-metal 1 : 2 nitrilotriacetate complexes

H 2 [M II (HNTA) 2 ]·xH 2 O complexes of eleven divalent metals were prepared. These complexes were characterized via elemental analysis, IR spectra, TGA, DTA and 1 H NMR. pKa 1 and pKa 2 of these acids were determined together with their log β 1 and log β 2 as metal complexes.
