摘要：

The structure re-refinement of tetragonal PbSnF4 was executed using data reported earlier. The rms amplitude in M2(Sn) site is larger in (001) plane than along the c-axis and the thermal vibrations of F3 fluorine ions are very large, i.e. B-eq = 12.415(20) A(2). M2F(8) polyhedra form a distorted cube. The fluorine ions on the F3 site are present between the M2 ion layers. The fluorine ions on the F3 site are located between the M2 ion layers and their weak bonds to Sn ions play an important role in the conduction. The ionic conductivity in the (001) plane is higher than that in the [001] direction.
