      Stacking interactions; biligand metal-phenanthroline-amino acid complexes

    • Abstract


      Biligand complexes of the type metal/o-phenanthroline/amino acid, where metal = Co2+, Ni2+, Cu2+, Zn2+, Cd2+; and amino acid = β-phenyl alanine or tryptophan have been found to show inter-ligand stacking interactions in aqueous solutions. This interaction has been evaluated quantitatively from a knowledge of the formation constants of these complexes (and that of the identical biligand complex with α-alanine) as determined by potentiometric pH titration at25°C and an ionic strength,I=0·2 (mol dm−3, KNO3) by following the Irving-Rossotti approach. The sequence of interaction is tryptophan > β-phenyl alanine.
