Complexation of trivalent lanthanide cations with amino(O-alkyl)methylenephosphonic acids as the closest organophosphorus analogues of nitrilotriacetic acid

Year: 2025

Type: article

Abstract: The complexation of new complexones, analogues of nitrilotriacetic (H3NTA) and nitrilotrimethylenephosphonic (H6NTP) acids containing monobasic (O-alkyl)methylenephosphonic fragments as donor groups, with trivalent cations of lanthanides was studied. The stability and deprotonation constants of 1:1 complexes and the fractional distribution of complex forms were determined using pH-metric titration in combination with mathematical modeling. The complexation properties of N-[(O-butyl)hydroxyphosphorylmethyl]iminodiacetic acid were compared with those of H3NTA based on the linear free-energy relationships.
