We carried out single-crystal X-ray diffraction measurements of β-PbF2 (quenched from 970 K) in the temperature range 131 to 298 K. The structure was refined to R = 0.008 at 131 K and R = 0.008 at 298 K by the least-squares methods, using about 80 reflections. The behavior of the one independent mobile fluorine ion could not be attributed to split atoms but instead was due to anharmonic thermal vibration.
