The (3 + 2)D structure of oxygen deficient LaSrCuO3.52

Abstract

The (3 + 2)D modulated structure of the oxygen deficient compound LaSrCuO3.52 was determined using a combination of electron diffraction and neutron diffraction. The cell parameters are a = b = 3.7587(3) Å, c = 13.0074(9) Å, α = β = γ = 90°, superspace group I4/mmm (αα0, αα0)00 mg, α = 0.2222(3), Rp = 4.5%, R0 = 2.1%, R1 = 4.9%. The oxygen vacancies are located in the CuO2−δ plane and are ordered with the oxygen atoms, creating three different oxygen environments for the Cu atoms: CuO4 squares, CuO5 pyramids and CuO6 octahedra.
