heal.abstractThe interactions of Et2SnCl2 with 5'-IMP and 5'-GMP have been studied in aqueous solutions by H-1-and P-31-NMR spectroscopy as a function of pH. At low pH values (<4.0) Sn(IV) interacts with the pyrophosphate oxygens of these nucleotides, At intermediate pH values (4-9.5) no interaction of the metal with the nucleotides take place, while at pH > 9.5 the sugar O-2' and O-3' atoms are the preferred coordination sites. Tn addition, the solid adducts obtained from aqueous solutions at pH = 3-4 of the above interactions correspond to formulae; (Et2Sn)(2)(5'-IMP)(2)(H2O) and (Et2Sn)(3)(5'-GMP)(2)(OH)(2)(H2O)(2) as their elemental analysis show. IR spectra and solid state C-13, P-31-NMR spectra Sn-119 Mossbauer and solution Sn-119-NMR spectra once more confirm the pyrophosphate involvement in bonding with Sn(IV) in oligomeric or polymeric structures and trigonal bipyramidal or octahedral geometries.
