• Resumen

  • The crystal structure of the new CuFeInTe_(3) quaternary compound was studied by the Rietveld method from powder X-ray diffraction data. The CuFeInTe_(3) compound crystallize in the tetragonal CuFeInSe_(3) -type structure with space group P2c (Nº 112), and unit cell parameters a = 6.1842(1) Å, c = 12.4163(2) Å, V = 474.85(1) Å^(3). The density of CuFeInTe_(3) is rx = 5.753 g cm^(−3). The reliability factors of the Rietveld refinement results are R_(p)= 5.5%, R_(wp)= 6.1%, R_(exp)= 4.7%, and S= 1.3. The powder XRD data of CuFeInTe3 are presented and the figures of merit of indexation are M_(20) = 79.4 and F_(30) = 43.3 (0.0045, 154).
