“…The new antimonide YbIrSb extends the series of rare earth antimonides REIrSb [44,45]. The cell volume of YbIrSb is smaller than the cell volume of the thulium compound and thus smoothly fits the lanthanoid contrac- [9,16,17] tion.…”

Europium / Ytterbium / Antimonides / Magnetic properties / Mössbauer spectroscopy / Single crystal structure analysis / X-ray diffraction Abstract. The equiatomic antimonides EuTSb (T ¼ Cu, Pd, Ag, Pt, Au) and YbIrSb were synthesized from the elements in sealed tantalum tubes in an induction furnace. The samples were investigated by powder X-ray diffraction and the structures were refined on the basis of single crystal X-ray diffractometer data:166 F 2 values, 8 variables for EuAgSb, a ¼ 467.1(2), c ¼ 848.8(3) pm, wR2 ¼ 0.042, 162 F 2 values, 8 variables for EuAuSb, and TiNiSi type, space group Pnma, a ¼ 762.5(3), b ¼ 469.1(1), c ¼ 792.1(1) pm, wR2 ¼ 0.046, 670 F 2 values, 20 variables for EuPdSb, and a ¼ 700.7(1), b ¼ 444.68(8), c ¼ 781.3(1) pm, wR2 ¼ 0.075, 592 F 2 values, 20 variables for YbIrSb. The structures are ordered superstructure variants of the aristotype AlB 2 with planar T 3 Sb 3 hexagons in EuTSb (T ¼ Cu, Ag, Au) and puckered T 3 Sb 3 hexagons in EuTSb (T ¼ Pd, Pt) and YbIrSb. TiNiSi type EuPtSb was characterized via powder data: a ¼ 759.8(3), b ¼ 465.4(3), c ¼ 791.4(3) pm. Temperature dependent magnetic susceptibility measurements indicate antiferromagnetic ordering for all compounds. The samples were additionally characterized by 121 Sb and 151 Eu Möss-bauer spectra.

“…The Ir--Sb distances within the three-dimensional [IrSb] network range from 262 to 274 pm, close to the sum of the covalent radii of 267 pm [39]. For further crystal chemical details on the REIrSb antimonides we refer to the original work with the structure refinements of SmIrSb [44] and CeIrSb [45].…”

“…Such small crystals can often directly be separated from long-term annealed samples by mechanical fragmentation. Better crystal quality can be obtained by an additional annealing process in an induction furnace, presented for CePdGe [31] and also applied to CeIrSb [32].…”

“…The basic crystallographic data of the CeTXH x hydrides are listed in Table 3. Only CeNiSn, CePdSn, CeRhSb, and CeIrSb form stable hydrides that keep a TiNiSi-type metal substructure, leading to CeNiSnH [47,82,236], CePdSnH [49], CeRhSbH 0.2 [89], and CeIrSbH 0.8 [32]. While the stannides absorb a full equivalent of hydrogen per formula unit, much smaller amounts have been observed for the antimonides.…”

Intermetallic compounds with the equiatomic composition CeTX that crystallize with the orthorhombic TiNiSi-type structure can be synthesized with electronrich transition metals (T) and X = Zn, Al, Ga, Si, Ge, Sn, As, Sb, and Bi. The present review focusses on the crystal chemistry and chemical bonding of these CeTX phases and on their physical properties, 119 Sn and 121 Sb Mössbauer spectra, high-pressure effects, hydrogenation reactions and the formation of solid solutions in order to elucidate structure-property relationships. This paper is the final one of a series of four reviews on equiatomic intermetallic cerium compounds [Part I

Structure D 2000Structure, Magnetic and Electrical Properties of CeIrSb and Its Hydride CeIrSbH 0.8 . -CeIrSb absorbs hydrogen at 573 K and 4 MPa, leading to the formation of CeIrSbH0.8. Both compounds crystallize with the TiNiSi-type structure in the space group Pnma with Z = 4 (powder and single crystal XRD). Hydrogenation induces both an increase of the cell volume and a strongly anisotropic expansion of the unit cell. The hydrogen insertion into CeIrSb leads to a magnetic transition from intermediate valence to antiferromagnetic behavior (T N = 7.0 K) as indicated by magnetization, electrical resistivity, and specific heat measurements. -(GAUDIN, E.; CHEVALIER, B.; HERMES, W.; RODEWALD, U.
