摘要
The intramolecular aromatic-ring stacking interaction of mixed-ligand complexes Pd (A) (ATP )2- in the system Pd2+-A-ATP4- has been determined by 1HNMR,where A=1, 10-phenanthroline (Phen ). 2, 2'-bipyridyl (Bpy ) and L-tryptophan (Trp-) ; ATP4-= adenosine 5'-triphosphate. The result Indicates that it is the partial stacking between the indole ring of ATP4- and the heterocyclic ring of A that makes H (2), H (8) and H (1') in the ATP4- shift upfield significantly. Accordingly, the order of aromatic-ring interaction in the mixed-ligand complexes has been obtained as follows: Pd (Phen)(ATP)2- >Pd (Bpy) (ATP)2- >Pd (Trp) (ATP)3-.
