Abstract

The crystal structure of the new CuFeInTe3quaternary compound was studied by the Rietveld method from powder X-ray diffraction data. The CuFeInTe3compound crystallize in the tetragonal CuFeInTe3-type structure with space group P¹4 2c (N±112), and unit cell parameters a = 6.1842(1) ° A, c = 12.4163(2) ° A, V = 474.85(1) °A3. The density of CuFeInTe3is ½x = 5:753 g cm¡3. The reliability factors of the Rietveld refinement results are Rp= 5:5%, Rwp= 6:1%, Rexp= 4:7%, and S = 1:3. The powder XRD data of CuFeInTe3are presented and the figures of merit of indexation are M20= 79:4 and F30= 43:3 (0.0045, 154).
