“…In a strongly polar or protic solvent, such as those known to mediate SET-LRP, cuprous ions and halide ions are expected to be highly solvated. In a polar environment such as DMSO, dissociation of Cu I X and Cu II X 2 salts are expected. , This dissociation is aided by the presence of strongly chelating ligands such as multidentate N -ligands, providing [Cu I ] + /L and [Cu II X] + /L complexes. The structure of the N -ligand dictates the accessible geometries of the resulting complexes.…”

“…From our ongoing efforts to study the role of metal ions on the versatile coordination ability of adenine, we focus our attention on the effect of some divalent metal ions on the structure of free adenine. Literature review indicated that many studies have been devoted to the interactions of Zn 2+ and Cd 2+ (among other di-valent metal ions) with a variety of biomolecules, such as tethered nucleo-bases, or ATP, or adenosine chloroderivatives, or DNA itself [5][6][7][8][9][10][11][12]. Yet, very few papers investigated the interaction of free adenine with metal ions [2,4].…”

We are reporting the fluorescence quenching, IR, Raman, 1 H-NMR, and potentiometric studies for the Zn 2+ :adenine and the Cd 2+ :adenine systems under ambient conditions. IR and Raman spectra suggest that Zn 2+ and Cd 2+ interact with adenine but the modes of interaction differ. Fluorescence spectra indicate that the interaction involving Zn 2+ is more favorable than that of Cd 2+ , and this effect is due to the difference in ionic radii. 1 H-NMR, potentiometry, and speciation diagrams indicate the formation of strong metal ion adenine complexes. Potentiometric titrations of the heavier member of group 12 metals (Hg 2+ ) show similar results to that of Zn 2+ and Cd 2+ . Some differences in the 1 H-NMR experiments appeared between both (Zn 2+ and Cd 2+ ) compared to that of Hg 2+ . Due to the fluorescence quenching of adenine, adenine can be used as a sensor of Zn 2+ and Cd 2+ .
