Samples of lanthanum-strontium cuprate LaSrCuO3.61 are synthesized by a solid-phase method at 1473 K, in air. Electron diffraction patterns reveal low-intensity satellites whose position is described in the reciprocal space by the (3 + 2)-dimensional space group I4/mmm(αα0, α-α0)00mg. Using a five-layer cell LaSrCuO 4-δ|YSZ|LaSrCuO4-δ|YSZ|LaCuO 4-δ prepared by isostatic hot pressing, the ionic component of conductivity of LaSrCuO4-δ is determined (σ 1179 K = 3.8 × 10-3 S cm-1), which is commensurate with other mixed conductors based on complex oxides of cobalt and iron.
