Synthesis and electrochemistry of [Ru(2,2′-bpy)3]2[S2Mo18O62] at electrode–solvent (electrolyte) interfaces
Abstract
Addition of [Ru(bpy)3][PF6]2 to [(C6H13)4N]4[S2Mo18O62] in CH3CN resulted in the formation of analytically pure [Ru(bpy)3]2[S2Mo18O62]. Insolubility in CH3CN and solubility in DMF allow solid state and solution phase electrochemical data to be compared. Voltammetric studies of [Ru(bpy)3]2[S2Mo18O62] adhered to a glassy carbon electrode surface and placed in contact with CH3CN (0.1 M Bu4NPF6) indicate diffusion of ions within the solid occurs rapidly in order to achieve charge neutralisation required for
