Biological activity and Equilibrium studies of solution have been taken at constant ionic strength I= 0.1 mol/l NaNO3 and temperature 37+0.10C and the interaction of Ca (II) & Cd (II) divalent ions with Cytidine 5ˈ-triphosphate & NA. The deep formation of 1:1:1 ternary and 1:1:1:1 quaternary complex was inferred from the potentiometric titration curve. It was deduced that Cytidine 5ˈ-triphosphate acts as a primary ligand in the ternary complexes involving the NA. The complexation model for systems of Cytidine 5ˈ-triphosphate (CTP) and the NA with the transition metal ions have been established by the SCOGS Computer software from the potential metric data. The value of Δ log K show that the ternary complexes are less stable than the quaternary ones, suggesting that less interaction occur between the ligands in the ternary complexes. The order of the value of the stability constant of ternary complexes was M(II)CTP(NA) is less than M(II) Mʹ(II)CTP (NA).
