Sur l'existence d'un hexafluorotellurate(IV) de diammonium (NH4)2TeF6: mise au point

We present in this paper new developments which confirm that the product previously described as (NH4)2TeF6 actually contains tellurium (IV) atoms octahedrally coordinated by six fluorine atoms. It is shown that the product is a solid solution nNH4F, mTeF4 with n/m close to 2 and containing small amounts of HF.
