ABSTRACT:

The formation of ternary complexes of metal-guanosine thymidine, uridine or adenosine have been studied by potentiometrically at 15°, 25°, 35° and 45°C and 0.1 M (KNO3) ionic strength. The metal ions studied are Cu(II), Ni(II), Co(II), Zn(II), Mg(II) and Ca(II). The thermodynamic parameters, enthalpy and entropy changes for these ternary systems are calculated. The ΔΔH values are highly negative and ΔΔS are
negative for these systems. The exothermic enthalpy for the mixed nucleoside complexes may be attributed to the energy of stacking interaction in these systems.
