Rigid and Compact Binuclear Bis-hydrated Gd-complexes as High Relaxivity MRI Agents

The first binuclear Gd-complex of the 12-membered pyridine-based polyaminocarboxylate macrocyclic ligand PCTA was synthesized by C?C connection of the pyridine units through two different synthetic procedures. A dimeric AAZTA-ligand was also synthesized w
