Abstract:The X-ray diffraction data of ErCoSn has been reported and the XRD pattern was refined by Rietveld method. The compound ErCoSn is orthorhombic with space group Pnma(62), a=7.1341A, b=4.5045A, c=7.4611A, V=239.77 A³, D_x=9.553 g·cm^-3 and Z=4 formula units per cell. The R factors R_p=11.48%, R _wp=14.84% and the figure of merit F₃₀=52(0.0093, 62) were obtained.

Key words: ErCoSn; X; ray powder diffraction; Rietveld refinement
