“…On the other hand, the uv and 'H-nmr spectra of both pyrimidine derivatives show the normal bands and signals, respectively, for these type of compounds (37)(38)(39)(40)(41)(42)(43). Proton nmr measurements for DATP support the presence of a tautomeric equilibrium between the thione and mercapto forms in DMSO solution, and therefore, C, symmetry has been proposed for both molecules.…”

Interaction of Pd(II), Pt(II), Ag(I), and Au(III) with 4,6-diamino-2-thiopyrimidine (DATP) and 4,6-diamino-2-methyl-thiopyrimidine (DAMTP) in aqueous medium resulted in the formation of new complexes which have been characterized by elemental analysis, ir, 1H-nmr spectroscopic techniques, magnetic susceptibility measurements in the solid state, and conductivity measurements in DMF solution. The ir and 1H-nmr spectra were consistent with coordination involving the non-protonated ring nitrogen atom, the exocyclic sulphur atom, or N,S-chelation.
