The clearest diffraction signature of the dehydration is the separation of the {110} and (002) reflections, which are near coincident in the hydrate, but do not overlap in the anhydrate [Fig. ]. As with the other M[Bi(SCN) 6 ] frameworks, this apparent peak overlap does not correspond to any change in framework symmetry, but merely results from the near cubic pseudo-symmetry of the metal substructure.
