Abstract

The crystal structure of Ba₃NiRuSbO₉ has been refined by Rietveld analysis of neutron powder diffraction data: space group P6₃ mmc, a = 5.7856(3), c = 14.2321(4) A ̊ at 295K. The phase adopts a 6H-BaTiO₃-like structure, with Ni²⁺ exclusively occupying the vertex-sharing octahedra and a random distribution of Ru⁵⁺ Sb⁵⁺ on the face sharing sites. A magnetic susceptibility study shows that Ba₃NiRuSbO₉ follows an approximate Curie-Weiss law (μ_av = 3.50μ_B, υ = -25 K) down to 80 K, though a slight deviation from linearity at lower temperatures is indicative of some short-range magnetic order.
