Abstract
Two new isostructural mixed-valence tellurium oxides, CsTe1.625W0.375O6 (1) and RbTe1.5W0.5O6 (2), have been synthesized by solid-state reaction. The single crystals of obtained compounds have been characterized by single-crystal X-ray diffraction analysis. Both compounds have β-pyrochlore-type structure (cubic system, space group Fd-3m, Z = 8) and the following unit cell parameters: a = 10.5437(2) Å in (1) and a = 10.3949(3) Å in (2). The structural features have been investigated, and the distortions of the building blocks [MO6] (M = Te, W) have been found. The oxidation states of tellurium have been confirmed by X-ray photoelectron spectroscopy. The thermal behavior of obtained compounds has been studied.
