Conformational and Coordination Equilibria on DOTA Complexes of Lanthanide Meta...
Aime, Silvio; Botta, Mauro; Fasano, Mauro; Marques, M. Paula M.; Geraldes, Carlos F. G. C.; Pubanz, Dirk; Merbach, André E.A variable-temperature, -pressure, and -ionic strength 1H NMR study of the DOTA complexes of different trivalent cations (Sc, Y, La, Ce → Lu) (DOTA = 1,4,7,10-tetraaza-1,4,7,10-tetrakis(carboxymethyl)cyclododecane) yielded data that are in contradiction with the hitherto used model of only two enantiomeric pairs of diastereoisomers that differ in the ligand conformations. A two-isomer equilibrium cannot explain...
