X-ray Powder Diffraction Data and Structure Refinement of TeO 3

Abstract The structure of TeO 3 , first published by Dumora and Hagenmuller (1968), was redetermined from new X-ray data collected with a powder diffractometer using space group R3̄c with a = 4.901(2), c = 13.030(4) Å, V = 271.05(8) Å 3 and Z = 6. Intensity data were obtained with CuKα, radiation (λ = 1.540598 Å). Structure refinement was performed with 49 reflections and led to R = 0.058. The material is isostructural with FeF 3 . Powder data are given.
