Subject:
anions; antimony; cations; ferrimagnetic materials; magnetic properties; magnetism; mixing; nickel
Abstract:
... The first mixed germanato-antimonato derivative of the {V₁₄E₈O₄₂} (E=semi-metal) cluster archetype has been synthesized under hydrothermal conditions and isolated as {Ni(phen)₃}₂[α-Vᴵⱽ₁₄Sbᴵᴵᴵ₅Geᴵⱽ₃O₄₂(OH)₃(H₂O)]· ≈16H₂O (phen=1,10-phenanthroline). In the cluster anion, seven of the eight hetero-metal positions are occupied by disordered Ge/Sb atoms, while one position is fully occupied by Sb atoms ...

Abstract:
... Several rare earth metal containing pseudo-ternary compounds in the RE₂TAl₃ series (RE=Sc, Y, La–Nd, Sm, Gd–Lu; T=Ru, Rh, Ir) have been synthesized from the elements by arc-melting or in tantalum capsules. Within the Rh series, the compounds with RE=La–Nd crystallize in the cubic MgCu₂-type (Fd3̅m) structure. For Sm besides the cubic Laves phase also the hexagonal Laves phase (MgZn₂ type, P6₃/mmc) ...

Abstract:
... The ternary rare earth transition metal-indides RE₃T₂In₄ (RE=Dy–Tm; T=Pd, Ir) were obtained from high-temperature reactions in sealed niobium ampoules. These indides adopt a hexagonal structure of the Lu₃Co₁.₈₇In₄ type (space group P6̅), a ternary ordered superstructure of the aristotype Fe₂P. The structures of three different compounds were refined from single-crystal X-ray diffractometer data: a ...
