摘要：

A series of diaminoalcohols (1,5-diaminotriols and 1,6-diaminotetrols) have been synthesised and their co-ordination abilities towards Cu-II studied by potentiometry and spectroscopic techniques (UV/VIS, EPR and CD). Both amino groups act as anchoring sites for two metal ions. Thus, two independent NH2, O- chelates are formed leading to dimeric complexes in which two metal ions are bound to two N-terminal atoms of the 1,5- or 1,6-diaminoalcohols. In all cases studied both ligand conformation and absolute configuration have a distinct impact on the stabilities of the complexes formed.
