Complex formation between [(η6-p-cym)Ru(H2O)3]2+ and oligopeptides containing three histidyl moieties

Supported by DFT calculations, formation of stable mononuclear (N1Im, N1Im, N1Im) coordinated complexes was found in the [Ru(η6-p-cym)(H2O)3]2+-Ac-HAHH-NH2 or -Ac-HAHAH-NH2 systems in slow processes to model the metal ion binding capabilities of surface-accessible histidyl imidazoles of albumin and transferrin.
