N2  - The complexation of Zn2+ by hydroxyethyl- and bis(hydroxyethyl)-1,4,7-triazacyclononane ((2) and (3)) in aqueous solution at 298.2 K and I = 0.10 mol dm&#8722;3 (NaNO3) is characterized by log(K/dm3 mol&#8722;1) = 10.45 &#177; 0.05 and 11.32 &#177; 0.02 and a deprotonation assigned to coordinated water is characterized by pKa = 8.87 &#177; 0.11 and 8.50 &#177; 0.03, respectively. For the analogous Cd2+ complexes log(K/dm3 mol&#8722;1) = 8.74 &#177; 0.02 and 9.79 &#177; 0.02, respectively, and no deprotonation of coordinated water is detected. The synthesis of (2) is described.
