Abstract
The crystal structure of the CeRh2Sb2âx 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: CeRh2Sb2âx (x = 0.34) (crystal I, as-cast alloy): a = 4.4925(11) Ã
, c = 10.1778(26) Ã
, VÂ =Â 205.41(9)Â Ã
3, Ï = 9.530 g cmâ3, μ = 31.468 mmâ1, R1 = 0.0431, wR2 = 0.1187 for 103 reflections with I > 2Ï(Io); CeRh2Sb2âx (x = 0.405) (crystal II, as-cast alloy): a = 4.4781(9) Ã
, c = 10.1652(20) Ã
, VÂ =Â 203.85(7)Â Ã
3, Ï = 9.603 g cmâ3, μ = 31.710 mmâ1, R1 = 0.0397, wR2 = 0.0857 for 116 reflections with I > 2Ï(Io); CeRh2Sb2âx (x = 0.24) (crystal III, annealed at 770 K sample): a = 4.5106(7) Ã
, c = 10.2442(16) Ã
