MIXED SB-5+ RU-5+ OXIDES - THE CRYSTAL-STRUCTURE OF BA3NIRUSBO9

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 (μav = 3.50μB, υ = -25 K) down to 80 K, though a slight ...
