Magnetic properties of a quaternary oxide Ba 3 NdRu 2 O 9 are reported. This compound adopts the 6H-perovskite structure with space group P6 3 /mmc, in which the cation sites within the face-sharing octahedra are occupied by ruthenium ions and those within the corner-sharing octahedra are occupied b

Crystals of Ba 5 Ru 1.6 W 0.4 Cl 2 O 9 were prepared in a BaCl 2 flux and investigated by X-ray diffraction methods. The structure of this new compound was solved and refined in the hexagonal symmetry space group P6 3 /mmc with a)2(718.5؍ A > , c؍ 24.839(2) A > , and Z2؍ to a final R of 0.0383
Magnetic properties of quaternary oxides Ba 3 MRu 2 O 9 (M ؍ Y, In, La, Sm, Eu, and Lu) are reported. Rietveld analyses of the X-ray di4raction data indicate that they adopt the 6Hperovskite structure and have the valence state of Ba 3 M 3؉ Ru 4.5؉ 2 O 9 . All compounds are nonmetallic at least ov
