Abstract

The six platinum complexes of formula [Pt(LL)(NuO) 2]Cl 2, where LL is o-phenylenediamine, 4,5-dimethyl- o-phenylenediamine or 2,2′-bipyridyl and NuO is a nucleoside such as guanosine or inosine, have been prepared by interacting an appropriate dichlorodiamine-platinum(II) with an appropriate nucleoside in excess. The resulting complexes have been characterized by chemical analysis and by ultraviolet-visible, infrared and 1H NMR spectroscopy. The 1H NMR study has established the binding of guanosine and inosine to platinum through N 7. The dicationic nature of the complexes has been established by conductivity measurements which show them to be 1:2 electrolytes.
