“…In (NH 4 ) 2 TeCl 6 the partial substitution of (NH 4 ) + by an other alkali may give a wide range of substitutional solid solutions, which opens up possibilities for preparing new materials with gradually varying properties. This work is a part of our systematic physico-chemical investigation of mixed-alkali hexachlorotellurates (Karray et al , 2003, 2004, 2006). We present here the Rietveld crystal structure analysis of [Cs 0.86 (NH 4 ) 0.14 ] 2 TeCl 6 obtained from powder diffraction data.…”

The crystal structure of cesium ammonium hexachlorotellurate [Cs0.86(NH4)0.14]2TeCl6, has been determined using X-ray powder diffraction techniques. At room temperature, the title compound crystallizes in the cubic space group Fm3m, with a lattice parameter a=10.470(17) Å. The Rietveld refinement of the structure led to final confidence factors Rp=0.0338 and Rwp=0.0487. The structure of [Cs0.86(NH4)0.14]2TeCl6 belongs to the large family of K2PtCl6-related structures. The H atoms of the ammonium group are orientated with its apex toward Te atoms as seen in the related compound (NH4)2SiF6. An IR spectroscopic study was performed to confirm the results of the diffraction method, notably concerning the presence of the ammonium group.
