A second lanthanum ruthenium oxide with the formula La3RuO7 is reported. This compound, β-La3RuO7, crystallizes in the P21/c space group with a unit cell of a = 8.8388(3) Å, b = 5.6960(1) Å, c = 12.5830(3) Å, and β = 104.729(1)°, 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 μeff = 3.92 μB and a Weiss constant of θ = -70 K.
