Description
The crystal structure of the CeRh2Sb2-x compound was studied by powder and single crystal X-ray diffraction from as-cast and annealed at 770 K alloys. The compound crystallizes with a CeGa2Al2 structure type, space group I4/mmm: CeRh2Sb2-x (x = 0.34) (crystal I, as-cast alloy): a = 4.4925(11) A, c = 10.1778(26) A, V = 205.41(9) A3, ρ = 9.530 g cm-3, μ = 31.468 mm-1, R 1 = 0.0431, wR 2 = 0.1187 for 103 reflections with I > 2σ(I o); CeRh2Sb2-x (x = 0.405) (crystal II, as-cast alloy): a = 4.4781(9) A, c = 10.1652(20) A, V = 203.85(7) A3, ρ = 9.603 g cm-3, μ = 31.710 mm-1, R 1 = 0.0397, wR 2 = 0.0857 for 116 reflections with I > 2σ(I o); CeRh2Sb2-x (x = 0.24) (crystal III, annealed at 770 K sample): a = 4.5106(7) A, c = 10.2442(16) A, V = 208.42(6) A3, ρ = 9.392 g cm-3, μ = 31.014 mm-1, R 1 = 0.0494, wR 2 = 0.1069 for 122 reflections with I > 2σ(I o); Bruker SMART CCD, data corrected for absorption using SADABS, structure refinement-WinGX 1.70
