文摘The stability constants of the ternary mixed ligand complex Cu(pdphen)(ATP)(2-), where pdphen is the planar ligand pyrido[3,2-f][1,7] phenanthroline, were determined by potentiometric pH titration in water,and in 30 and 50%(v/v) aqueous dioxane solutions. It has been observed from this information that a stronger stacking interaction between pdphen and the base pf ATP exists and decreases with decreasing selvent polarity i.e.,inereasing amounts of dioxane in the solvent mixture.
