PbSnI4 has been prepared from equimolar amounts of PbI2 and SnI2. X-ray and DSC measurements show the material to be uniphase in the temperature range 30 to 400°C; it has a tetragonal structure and melts at 379°C. The electrical conductivity is mainly ionic with an ionic transport number greater than 0.99 at 200°C. Conductivity at room temperature is 2.56 × 10−8 Ω−1 cm−1 while the value at 200°C is 1.25 × 10−6 Ω−1 cm−1.
