摘要
Thermodynamic property of the title complex compounds was studide by pH method. The stability constans of binary and ternary complexes of cobalt(Ⅱ )-bipyridylα-amionoacids were determined at 25.0±0.1 ℃ in the presence of 0.1mol·dm-3 KNO3. The relationships between stability of complexes and strength of d-p back-donation bonding formed for cobalt(Ⅱ )-bipyridyl were discussed. The kinetic property of ternary system was studied by temperature-jump technique. The formation rate constants of ternary complexes were determined. The results show that thermodynamic stability and reaction rate related to the strength of acid and base of ligends. It was found again that linear free energy relationships exist.
