“…Besides the binary series of RE 2 Sb antimonides and RE 2 Bi bismutides (RE ¼rare earth element), a larger variety of ternary rare earth-containing representatives of this structure are known, e.g. the series of REScSi silicides [3], REScGe germanides [4], and REScSb antimonides [5]. The distinctly smaller size of scandium allows for a complete ordering of the two rare earth sites leading to the formation of the CeScSi-type structure.…”

Their ordered La 2 Sb type structures, with space group I4/mmm, were refined from single crystal X-ray diffractometer data: a ¼428.94(6) and b ¼1570.5(3) pm, wR2 ¼ 0.0395, 309 F 2 values for NdScSi and a ¼431.2(1) and c ¼1581.3(5) pm, wR2 ¼ 0.1220, 227 F 2 values for NdScGe, with 11 variables per refinement.Hydrogen insertion was performed on both Nd-based intermetallics by solid/gas reaction. Hydrogen uptake keeps the pristine compound space group but yields an anisotropic expansion of the unit cell with a large increase of c ( E þ7%) and a slight decrease of a ( E À 1.7%) parameters. Hydrogen absorption at 350°C and under 5 bar of H 2 pressure shows that the hydride NdScSiH 1.48(5) is formed. An in-situ neutron diffraction study during the deuteration of NdScSi reveals for the first time in a CeScSi-type compound, the possibility to fill two interstitial sites with deuterium atoms, leading to the composition NdScSiD 1.5 for the deuteride adopting then the La 2 Fe 2 Se 2 O 3 -type structure.From magnetization measurements, we evidence that hydrogenation strongly reduces the Curie temperature of NdScSi (T C ¼ 175 K) and NdScGe (T C ¼194 K) since NdScSiH 1.5 and NdScGeH x undergo a magnetic transition at 4 K and around 2 K, respectively.

New Ternary La 2Sb-Type Compounds, ScRESb (RE: La, Ce, Pr, Nd, Sm, Tb), and the Oxygen Stuffed Variant Sc 4Yb4Sb4O. -The compounds ScLnSb (Ln: La, Ce, Pr, Nd, Sm, Tb) are prepared by solid state reaction of Sc metal and LnSb (Ta ampules, 1770 K, 36 h and 1520 K, 60 h). Sc 4Yb4Sb4O is obtained under similar conditions by replacing stoichiometric amounts of Sc by Sc 2O3. The samples are characterized by single crystal XRD and magnetic susceptibility measurements. The compounds crystallize in the tetragonal space group I4/mmm (Z = 4) with an ordered variant of the tetragonal La 2Sb-type structure. The magnetic susceptibility of ScCeSb, ScPrSb, and ScNdSb reveals Curie-Weiss behavior. -(NUSS, J.; JANSEN, M.; Z. Anorg. Allg. Chem. 640 (2014) 5, 713-718, http://dx.

Incorporating different anions with varied ionic sizes and charges is a rapidly growing approach to bring out unusual physical properties among various classes of solid-state materials, pnictides and chalcogenides in particular. This minireview is focused on hetero-anionic materials based on the pnictogens, which have been demonstrated to offer an impressive diversity of crystal chemistry and electronic structures. In addition, many pnictide oxides or oxypnictides, over the course of the last decade, have been shown to exhibit a broad spectrum of superconducting, magnetic, and semiconducting properties. However, the structural diversity of the mixed-anion materials is far greater than the several known structure types, or their variants, of the well-known layered superconductive materials. Therefore, with this treatise, we aim to provide a comprehensive overview of the crystal chemistry of pnictide oxides by recounting almost 40 different structures of such ternary and multinary compounds. In addition to the structural aspects, we also highlight some of the challenges associated with the synthesis, and briefly summarize reported, to date, physical properties of this remarkable class of solids.
