Samples were prepared from equimolar amounts of PbI2 and SnI2. Differential scanning calorimetry and X-ray techniques revealed that the material was single-phase at temperatures ranging from 30 to 400C. It also had a tetragonal structure, and melted at 379C. It was found that the conductivity was mainly ionic; with a transport number which was greater than 0.99 at 200C. The room-temperature conductivity was equal to 2.56 x 10-8S/cm, while the conductivity at 200C was equal to 1.25 x 10-6S/cm.
