摘 要:The stability constants of binary ML ̄2+ complexes formed by Zn ̄2+ or Cd2+ (M2+) andisoquinoline or benzimidazole(L) and ternary M(ATP)L2- complexes containing ATP in additionwere determined by potentiometric pH titration in aqueous solution It has been found that there isan intramolecular stacking interaction between the heteroaromatic N-Base ligands and the basepat of ATP in the ternary complexes, this interaction may have rlation to the structure of thearomatic rings of the L ligands.
