Abstract:

The electric conductivity of nanocluster polyoxomolybdates (POMs) Mo-132 and Mo72Fe30 with a keplerate structure in aqueous solutions, of these POMs in the solid state, and of Mo-138 with a toroidal structure was studied. Data on the concentration dependence of the equivalent electric conductivity in solutions and on the specific conductivity of the solid samples were obtained. Solid Mo-132 showed predominantly electron type of conductivity at nearly room temperatures due to the presence of molybdenum at different oxidation levels; Mo72Fe30, which has metal components at the highest oxidation levels, was found to be poor electric conductor; Mo-138, which has a lower content of low-valence molybdenum than Mo-132, showed intermediate conductivity and a reversible transition between the proton and electron types of conductivity.
