Potentiometry and NMR studies of 1,5,9-triazacyclododecane-N,N',N''-triacetic a...
Cortes, S.; Brucher, E.; Geraldes, C. F. G. C.; Sherry, A. D.A new chelating macrocycle, 1,5,9-triazacyclododecane-N,N’,N’’-triacetiacc id (DOTRA), has been synthesized, and its complexes with Zn2’, Cd2+, Ca2+, Mg2+, and Mn2+ have been examined by potentiometry and NMR spectroscopy. The first protonation constant of the free ligand (log K, = 12.8) was determined spectrophotometrically, while the remaining were evaluated from potentiometric data (log K2 = 7.55, log K, = 3...
