Abstract The electron transport and magnetic properties of the AxP8W32O112 bronzes (A = K, Rb, Tl) have been studied as a function of temperature. These compounds are characterized by a Pauli paramagnetism. The evolution of conductivity, ranging from 1260 (Ωcm)−1 to 1610 (Ωcm)−1 at 300K is characteristic of a metal. Owing to the presence of ReO3 type slabs, these properties can be interpreted by the band model conduction developed by Goodenough for NaxWO3 bronzes.
