Abstract
Formation of nickel(II) complexes with ethylenediaminetetraacetic acid (Edta) and 2,2′-dipyridyl (Dipy) has been studied by electronic absorption spectroscopy. Mathematical modeling has demonstrated that the most probable mathematical models to describe the experimental dependences of absorption on the medium acidity and concentration of solution components relies on the dissociation constants of the ligands (K i ) and stability constants (β) of homoligand, heteroligand, and polynuclear complexes of general composition [Ni m Dipy n Edta r ]2m − 4r (m = 1–4, n = 0–8, r = 0–1) as parameters. The reaction equilibrium constants and stability constants of the resulting complexes have been calculated. The structures of these complexes have been suggested.
