Abstract
The crystal structure of the CeRh2Sb2-x compound was studied by powder and single crystal X-ray diffraction from as-cast and annealed at 770K 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)angstrom, c= 10.1778(26)angstrom, V=205.41(9)angstrom(3), rho= 9.530g cm(-3), mu=31.468 mm(-1), R-1=0.0431, wR(2)=0.1187 for 103 reflections with I > 2 sigma(I-o); CeRh2Sb2-x, (x=0.405) (crystal II, as-cast alloy): a=4.4781(9)angstrom, c=10.1652(20)angstrom, V=203.85(7)angstrom(3), rho=9.603 g cm(-3) mu=31.710 mm(-1), R-1=0.0397, wR(2)=0.0857 for 116 reflections with I > 2 sigma(I-o); CeRh2Sb2-x (x=0.24) (crystal 111, annealed at 770K sample): a=4.5106(7)1 angstrom c=10.2442(16) angstrom, V=208.42(6) angstrom(3), rho=9.392 g cm(-3), mu=31.014 mm(-1), R-1 =0.0494, wR(2)=0.1069 for 122 reflections with I > 2 sigma(I-o); Bruker SMART CCD, data corrected for absorption using SADABS, structure refinement-WinGX 1.70.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
