| Abstract: The stability constants of ternary system of 1,4,7,10-tetraazacyclotridecane-11, 13-dioneα-aminoacid and 5-substituted phenanthroline were measured by pH method at 25.0±0.1℃,I= 0.1mol·dm-3KNO3. The coordinating ability of dioxotetraamine with copper(Ⅱ), the structure and the stability of copper(Ⅱ) complexes were discussed. The results show that d-p back bonding formed between phen and copper(Ⅱ). Hammett parameters of substituents influenced the stability of their copper(Ⅱ) complexes. |
