摘 要：The formation constants of ternary mixed ligand complex compounds formed fromCu（Ⅱ）-2,2 -bipyridyl （bipy） with N-（para-substituted phenyl） glycines （pRPhG）, Cu（Ⅱ）-1, 10-phenan-throline （phen） with N-（meta-substituted phenyl） glycines （mRPhG）, Cu（Ⅱ）--bipy/phen with someα-aminoacids （αA） have been determined by pH method at 25℃ in the presence of 0.10 M *** was found that linear free energy relationships do exist between the stability of ternary complexcompounds and the base strengths of the ligands in all four ternary systems investigated. The stabi-lity of the ternary complex compounds was discussed in terms of ΔlogKMand log X values. It wasfound again that linear relationships exist between Δ log KM, log X and p K2in the Cu （Ⅱ）-phen-mRPhGternary system.
