In aqueous solution, bis(nucleoside) complexes formed by the reaction of cis-[Pt(NH3)2(H2O)2]2+ with an excess of either adenosine (ado) or a mixture of adenosine and guanosine (guo) undergo a slow N7--> N1 linkage isomerisation in the adenine moiety. The isomerisation probably involves the breaking
