摘要：

The protonation and ZnII/CuII complexation constants of tripodal polyamine ligand N-1-(2-aminoethyl)-N-1-(1H-imidazol-4-ylmethyl)-ethane-1,2-diamine (HL) were determined by potentiometric titration. Three new compounds, i.e. [H-3(HL)](ClO4)(3) (5), [Zn(HL)Cl](ClO4) (6) and {[Zn(L)](ClO4)}(n) (7) were obtained by reactions of HL center dot 4HCl with Zn(ClO4)(2)center dot 6H(2)O under different reaction pH, and they were compared with the corresponding Cu-II complexes reported previously. The results indicate that the reaction pH and metal ions have remarkable influence on the formation and structure of the complexes.
