By use of synchrotron radiation, powder X-ray diffraction of ScSb and YSb with a NaCl-type structure has been studied up to 45GPa at room temperature. A first-order phase transition from the NaCl-type (B1) to a CsCl-type structure (B2) began to occur at around 28GPa for ScSb and at around 26GPa for YSb. Crystal data of the high-pressure phase of both antimonides are obtained. The high-pressure structural behavior of ScSb and YSb is similar to that of heavier LnSb (Ln=Dy-Lu). The B1-B2 transition for ScSb and YSb can be understood according to the rigid sphere model. The bulk moduli of ScSb and YSb are about 58GPa at ambient pressure.

Abstract: Thermoelectric materials have the potential to save energy by recycling the waste heat from many processes. These materials are under active development and consequently the understanding of the thermodynamics and phase equilibria of these systems is necessary. In this work we have performed a calorimetric investigation of some thermoelectric alloys, which do not contain toxic or extremely rare elements. The standard enthalpies of formation of some binary 4d and 5d antimony and transition metal (TM) compounds have been measured by high temperature direct synthesis calorimetry. The reported results are: YSb (–124.7 ± 4.7); Y5Sb3 (–111.1 ± 3.2); Zr5Sb3 (–65.4 ± 3.2); RuSb2 (–16.8 ± 1.5); RhSb3 (–33.8 ± 2.1); Pd3Sb (–54.0 ± 2.7); Hf5Sb3 (–55.4 ± 3.0); OsSb2 (–7.4 ± 4.0); IrSb3 (–45.5 ± 2.5); PtSb2 (–53.2 ± 1.8) in kJ/mol of atoms. We compare our results with some previously published measurements and with predicted values by ab initio calculations.

Single crystals of LnFeSb3 (Ln = Pr, Nd, Sm, Gd, and Tb) have been grown from excess Sb flux. The crystal structure consists of ∞2[FeSb2] octahedra separated by layers of Ln atoms and nearly square planar nets of ∞ 2[Sb2]. These compounds are metallic and display anisotropic magnetic properties. Long-range antiferromagnetic order is observed in the Sm, Gd, and Tb samples when the magnetic field is applied along the crystallographic a-axis. Evidence of magnetic ordering in all the samples is observed for the field applied parallel to the layers. The magnetic properties are well-described by considering only the magnetic interactions between the Ln 4f moments, with no contribution from the Fe sublattice. Herein, we report the crystal growth, structure, magnetization, transport, and chemical stabilities of the title compounds. The Royal Society of Chemistry.
