Abstract
The structure of BaTl0.5Sb0.5O3 has been investigated by powder X-ray diffraction, The profile refinement shows that the structure is of the (NH4)(3)FeF6-type, having a high degree of ordering between Tl and Sb , with the space group Fm (3) over bar m and lattice parameter a=8.380 9(1) Angstrom. The oxygen atoms are shifted away from the Tl toward th e Sb, creating an alternative arrangement of larger TlO6 and smaller S bO6 octahedra with the Tl-O and Sb-O bond distances being 2.21 and 1.9 8 Angstrom, respectively.
