The reactions of the dinuclear complex cysteinatomethylester platinum(II)-μ-dichlorocysteinatomethylester platinum(II),[Pt(O-MeCys)Cl] 2, with nucleosides have been studied in aqueous solutions. The isolated complexes correspond to the general formulae [Pt(O-MeCys)(nucl)Cl], where nucl = cytidine (cyd), inosine (ino) ,guanosine (guo), adenosine (ado), tri- and tetraacetyladenosine (trado, tetado) and triacetylinosine and guanosine (trino,trguo). The complexes were characterized by elemental analyses, conductivity measurements, IR, 1H NMR and 13C NMR spectra. The results indicate that the purine bases coordinate through both N(7) and N(1) with Pt(II), whenenver these are available, while cytidine does so through N(3). The PtN bond in this case is found weaker as compared to other similar bonds, due to the high trans influence of the opposite PtS bond.
