Complexes of types [Pd(CH3COO)(na)])xH2O, Hna=adenine (Hade) or guanosine (Hguo), x=2 · or 3; [Pd(CH3COO)2 (0.5 Hado)]2H2O, Hado=adenosine; [Pd(NH3)(na)(aa)3H2O, Hna=Hguo or inosine (Hino), Haa=glycine or alanine and [Pd(NH3)(gly)(0.5 ade)]2NO3H2O have been synthesised and characterized by elemental and thermal analyses, electronic, infrared, 1H NMR spectral and XPS studies. In acetato complexes, adeninate and guanosinate act as bridging ligand through the ring nitrogens N3 or N1 and N9, and N1 and N7 respectively giving polymeric structure while adenosine bridges the Pd(II) centers through N1 and N7. In amino acidato complexes, nucleosides coordinate through N1 to Pd(II) and adeninate bridges the two adjacent Pd(II) through N1 or N3 and N9.
