| Abstract: | The crystal structure of Na3RuO4 determined by powder neutron diffraction is reported. The structure consists of isolated tetramers of edge sharing RuO6 octahedra in the ab plane, creating isolated four-member plaquettes of Ru atoms comprised of two equilateral triangles sharing an edge. Magnetic susceptibility measurements reveal an antiferromagnetic transition at ∼29 K, with  . Neutron diffraction data indicate the onset of three-dimensional magnetic ordering at 29 K. |
