摘要：
second lanthanum ruthenium oxide with the formula La3RuO7 is reported. This compound, beta-La3RuO7, crystallizes in the P2(1)/c space group with a unit cell of a=8.8388(3)A, b = 5.6960(1) Angstrom, c = 12.5830(3) Angstrom, and beta = 104.729(1)degrees, as refined from powder neutron diffraction data. The two major structural motifs in this structure are isolated RuO6 octahedra and edge-sharing chains of OLa4 tetrahedra. Magnetic susceptibility measurements show this compound to have a magnetic moment of mu(eff) = 3.92 mu(B) and a Weiss constant of theta = -70 K. (C) 2002 Elsevier Science (USA).
