The electric conduction of NH₃K_3-xRb_xC₆₀ was studied using the cavity perturbation technique. It was confirmed that (NH₃)K_3-xRb_xC₆₀ was insulating between 4.5 and 250 K. Conductivity of (NH₃)K_3-xRb_xC₆₀ at 200 K was found to be 3-4 orders of magnitude smaller than those of K₃C₆₀ and (NH₃)NaRb₂C₆₀. Difference in conductivity of these materials showed that metal-insulator transition (MIT) in A₃C₆₀ systems was driven by the reduction of lattice symmetry from fcc to fcc.
