| Abstract: | The formation constants of ternary mixed ligand complex compounds (logK_(MAB~(MA)) formed from 1,10-phenanthroline or 2,2'-bipyridyl (A), N-(meta-substituted phenyl) glycines, (B, m-RphG, R=CH_3, H, CH_3O, Cl) with Nickel(Ⅱ), Cobalt(Ⅱ) and Zinc(Ⅱ) were determined by pH method at 25 ℃ in 30% (Volume) ethanol solution in presence of 0.1 mol·dm~(-3) NaClO_4 or 0.1 mol·dm~(-3) KNO_3. It was found that linear free energy relationships exist between the stability of ternary complex compounds and the base strengths of ligands in all six ternary systems investigated. The stability of the ternary complex compounds was discused in terms of ΔlogK_M values and HSAB theory. It was found that linear relationships also exist between ΔlogK_M and pK_2 in the Ni(II)-phen-m-RPhG ternary system. |
