Abstract

The formation constants of Cu(II)-[or Ni(II)]-bipy-N,N-bis(substituted phenyl)ethylenediamine were determine by pH method at 25? I = 0.1 mol/dm3(NaClO4) in 50% (v/v) dioxane solution Linear free energy relationships were found to exist between the formation constants of the ternary complex compounds and the protonation constants of the second ligands (i.e. log KMABMA = a-blogK1H). It was also found that the stability of the ternary complex is greater than that of the parent binary complex. This phenomenon could be explained by the formation of back p-bonding between metal ion and the first ligand.

Key words: STABILITY CONSTANT, COPPER COMPLEX, TERNARY COMPLEX, NICKEL COMPLEX, ETHANEDIAMINE, ACID-BASE EQUILIBRIUM, COORDINATE CHEMISTRY, BIPYRIDINE P, LIGANDS
