Abstract

The structure of La2CuSnO6 was determined by Rietveld refinement of time-of-flight powder neutron diffraction data. The structure was solved in space group P21/m with unit-cell parameters a = 8.510 (1), 6 = 7.815 (1), c = 7.817 (1) Å, and β = 91.15 (1)°. The structure is best described as a 2ap × 2ap × 2ap distorted perovskite with an unusual arrangement of B cations that produces distinct copper-oxygen and tin-oxygen layers. The structural aspects are similar to the high-temperature cuprate superconductors. The magnetic susceptibility versus temperature profile indicates the compound is not a superconductor above 5 K. The phase diagram of the LaO15–CuO–SnO2 system was determined at 980 °C in air. La2CuSnO6 is the only ternary compound in the system.
