The stability of the complexes of four pyridine-like ligands with Cu(ATP)^2- was studied and by comparing the stability constants of the ternary complexes [Cu(ATP)L]^2- with those of the binary complexes [CuL]²⁺,a stacking interaction between the pyridine ring and the purine ring of ATP is indicated.It is possible to interpret the antitumor mechanism of[Pt(NH₃)₈ (N-het)Cl]Cl in terms of this stacking interaction.
