Abstract
Using 1,4,8,11-tetraazacyclotetradecane (cyclam) and tris(2-aminoethyl)amine (tren) as building blocks a ditopic (2) and a polytopic (3) ligand were prepared. Their complexation potential towards Cu2+ and Ni2+ was studied by potentiometric and spectrophotometric techniques. The results show that in the case of 2 the first metal ion and in the case of 3 the first three metal ions added bind at the macrocyclic unit, whereas the metal ion added afterwards is coordinated by the tren unit. This allows to selectively prepare heteronuclear metal complexes.
