If your refinement looks good it doesn't necessarily mean your model is
true, just that you have a lot of parameters :-)
Negative temperature factors mean that your refinement is trying to add
intensity at high angles, the opposite of the temperature effect. This may
mean that you haven't correcte
The reason may be in the absorption (as noted by Alan Hewat) for capillary
samples or in the surface roughness effect for flat samples.

Hi, I wonder whether anyone has a cif file of Ca2MnTeO6 or at least
structural data?
Best,
