Özet
The interaction of Tl3+ with sodium salts of adenosine-5′-monophosphate (5′-AMP), guanosine-5′-monophosphate (5′-GMP), cytidine-5′-monophosphate (5′-CMP), thymidine 5′-monophosphate (5′-dTMP) in ratios 1 and 2 have been studied in neutral pH. The solid complexes were isolated and characterized by Fourier transform infrared (FTIR) and 1H NMR spectroscopy. In the Tl2(AMP)3, Tl3+ binds directly to N-7 and indirectly to the N-1 position of the pyrimidine ring and phosphate group with sugar moiety in C2′-endoanti. The crystalline salt of Tl2(GMP)3 show direct Tl-N-7 and Tl-PO3 (inner-sphere) binding. The conformation of ribose moiety in Tl2(GMP)3 is C3′-endoanti. In the Tl2(CMP)3, Tl3+ bind directly to N-3 and PO32- (inner-sphere). The conformation of ribose moiety in Tl2(CMP)3 is C2′-endoanti. In the Tl2(dTMP)3, Tl3+ bind indirectly to carbonyl group. The sugar moiety in Tl2(dTMP)3 is C3′-endoanti. © 2001 Elsevier Science B.V.
