A new heptadentate tripodal ligand leading to a gadolinium complex with an improved relaxation efficiency
摘要:
The new heptadentate tripodal ligand tpaa containing three
pyridinecarboxylate binding units reacts with Gd(III) in water
to give a thermodynamically stable complex which displays high
relaxivity.

for the two ligands. Quite surprisingly, the formation constant of the Eu(tpaam)Cl(3) complex in D(2)O at 298 K (log beta(110) = 2.34(4)) is very similar to the one reported for Eu(tpa)Cl(3) (log beta(110) = 2.49(4) at 298 K in D(2)O) indicating that the addition of three amide groups to the ligand tpa does not lead to any increase in stability of the lanthanide complexes of tpaam compared to those
