✦ Synopsis

The complexes formed by [(1)-2,3-P 2 Mo 2 W 15 O 61 ] 10-with vanadium(IV), manganese(II), cobalt(II), nickel(II), copper(II), and zinc(II) were synthesized. They were characterized by elemental analysis, IR, UV/Vis and 31 P NMR spectroscopy. Their electrochemical studies are complemented by those of the previously synthesized iron(III)-and Mo(VI)-substituted complexes. Among the main conclusions from the electrochemistry of all these compounds, it can be pointed out that only the iron(III) and the copper(II) ions within the complexes are reducible in the same potential domain as the molybdenum(VI) moieties. In the case of the iron(III) complex, it
