Abstract
Acid-base properties of 2,2′-{[(diisopropoxyphosphoryl)methyl]azanediyl}diacetic acid and its complexing ability towards alkaline-earth and transition metals have been studied by means of potentiometric titration. Comparative analysis of the determined stability constants and these of iminodiacetic and nitrilotriacetic acids has been performed. In comparison with iminodiacetic acid, the studied ligand has formed stronger complexes with alkaline earth metal ions and weaker complexes with transition metal ions; its complexes with the investigated cations have been weaker than these of nitrilotriacetic acid.
