Abstract
The synthesis of complexes of platinum and palladium with adenine is reported. The composition of these polycrystalline complexes was a 1 : 1 ratio of the ligand to the metal. The coordination sites of these compounds were investigated by means of infrared (IR) spectroscopic analysis. The mixed ligand complex, Cu (adeH2) (oxa) Cl·3/2H2O has been prepared. The complex was characterized by elementary and IR spectroscopic analyses. In case of Cu (adeH2) (oxa) Cl·3/2H2O, it was assumed that the nigrogen atom N9 of adenine coordinated to Cu2+ and that the N1 and N7 were protonated. From IR spectra of the complexes of platinum and palladium with adenine, it was supposed that N1 and N7 were the coordination sites.
