Crystal Structure, Magnetism, p>89p>Y Solid State NMR, and p>121p>Sb Mössbauer Spectroscopic Investigations of YIrSb
文摘
The ternary antimonide YIrSb was synthesized from the binary precursor YIr and elemental antimony by a diffusion controlled solid-state reaction. Single crystals were obtained by a flux technique with elemental bismuth as an inert solvent. The YIrSb structure (TiNiSi type, space group Pnma) was refined from single-crystal X-ray diffractometer data: a = 711.06(9), b = 447.74(5), c = 784.20(8) pm, wR2 = 0.0455, 535 Fp>2p> values, 20 variables. p>89p>Y solid state MAS NMR and p>121p>Sb Mössbauer spectra show single resonance lines in agreement with single-crystal X-ray data. YIrSb is a Pauli paramagnet.
