Abstrakt:	The synthesis of two tripodal iron chelating agents based on 8-hydroxyquinoline is described. The ligands consist of tris(2-aminoethylamine) (spacer) linked in 2- or 7- position to three 8-hydroxyquinoline units (allowing the complexation of iron). NMRstudy of these ligands in DMSO-d6solutions evidence intramolecular H-bond networks inducing conformational changes in relation to the protonation state of the tertiary amine.
