Crystal structure of Сu4SeTe

详细

Сu₄SeTe compound has been synthesized. A Сu₄SeTe sample was homogenized by annealing at 750 K for five days. An X-ray diffraction analysis based on powder diffraction data has revealed that the sample crystallizes into the trigonal system with lattice parameters а = 4.178 Å and с = 41.921 Å, sp. gr. \(R\overline 3 m\), Z = 6. Its crystal structure has been determined and refined by the Rietveld method. The final value of the reliability factor R_Bragg is found to be 0.0246.
