Tripodal hexadentate hydroxypyridin-4-ones are increasingly utilised as iron(iii) and gallium(iii) ligands, their attachment to proteins being particularly useful for positron emission tomography (PET). A widely studied tripodal ligand NTA(BuHP)<inf>3</inf>, which is reported to form 1:1 iron(iii) and gallium(iii) complexes in aqueous, media forms 2:2 complexes under physiological conditions. This important difference has implications for both iron chelation therapy and PET imaging. This journal is
