ABSTRACT Irving-Rossotti technique has been applied to study the formation constant of the reaction (Cu A)2+ + L− ⇌ (Cu AL)+ where A = dipyridyl and L = Glycine, α or β-alanine. Copper dipyridyl 1 : 1 is known to form at lower pH and is stable at higher pH when the secondary ligand gets bound. The values of the formation constant obtained in the mixed ligand systems are little less than the first formation constant of Cu-amino acid simple systems.
