The new ternary compound Pr117Co57Sn112has been successfully synthesized and studied by means of X-ray powder diffraction technique. The compound Pr117Co57Sn112crystallizes in a cubic Dy117Co57Sn112-type structure with space group Fm3¯m (No. 225) and lattice parameter a=30.8202 (5) Å. The figure of merit for the index F30is 80.4 (30). Crystal-structure of Pr117Co57Sn112has been successfully refined using the Rietveld method from X-ray diffraction data. The R-factors for the Rietveld refinement are Rp=0.077, Rwp=0.101 and Rexp=0.032. The temperature dependence of the magnetization for the compound was also investigated in the range from 85 to 305K. The experimentally determined magnetic effective moment is μeff=54.6μBper formula unit.
