Abstract: The formation of electrostatically linked complexes between [Ru(bpy)(3)]Cl-2 or [Ru(bpy)(2)(Mebpy-py)](PF6)(2) and (TBA)(6)alpha-[P2W18O62] or (TBA)(5)K-2 alpha(2)-[Fe-III(H2O) P2W17O61] in solution were studied by steady-state absorption and luminescence spectroscopy. The stoichiometry and global association constants of the formed complexes were obtained by the Job method. The formed complexes were characterized by H-1 and P-31 NMR spectroscopy and their ical properties compared to the precursor compounds were investigated by using the cyclic voltammetry method.
