Integrated X-ray intensities for MnF 2  have been gathered for all reflections up till sin  ϑ / λ  = 1.0 Å −1 . Ag Kα  radiation was used monochromated by a graphite monochromator. The distribution of  χ  2  = ( n  – 1)  s  2 / σ  2 ,  σ  2  =  υσ  P  2 , taken over 234 twice ( n  = 2) repeatedly measured intensities agreed best with the theoretical  χ  2  distribution, if all Poisson variances  σ  P  2  were multiplied by  υ  = 1.013. The agreement between symmetry equivalent intensities was checked by means of a  χ  2 -test and intensities having a  χ  2  larger than expected from statistics were rejected. Weighted least-squares refinement with anisotropic temperature factors yielded the goodness-of-fit parameter 1.7(1.06) and the agreement factors  R w   = 0.007(0.01) and  R  = 0.019(0.02), numbers in brackets were obtained if all reflections with sin  ϑ / λ  &lt; 0.7 were omitted. The attempt to refine cumulant tensors of rank 3 and 4 has not shown any significant deviation from harmonic motion for both atoms Mn and F. With the lattice constants  a  = 4.8734 and  c  = 3.3099 Å the fluorine position parameter was determined to  x  = 0.3050.
