Abstract Ac and dc electrical conductivity data are presented for two polynuclear metal cluster compounds Au55(PPh)3)12Cl6 and Pd561Phen36O200. The temperature dependence of the low field dc conductivity increases with electrical field, the rate of increase becoming stronger with decreasing temperature. These results are compared with data for granular metal systems, and a close correspondence is observed. The conductivity is found to increase with frequency in analogy to what is observed in amorphous systems. A scaling law for low frequencies that has been recently proposed is shown to describe the data quite well.
