Materials Data on Ba3Sr(CuO3)4 by Materials Project
Abstract
Ba3Sr(CuO3)4 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded to twelve O atoms to form BaO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, corners with eight BaO12 cuboctahedra, faces with two equivalent SrO12 cuboctahedra, faces with four BaO12 cuboctahedra, and faces with eight equivalent CuO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.82–2.90 Å. In the second Ba site, Ba is bonded to twelve O atoms to form BaO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, corners with eight equivalent BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, and faces with eight equivalent CuO6 octahedra. There are eight shorter (2.84 Å) and four longer (2.91 Å) Ba–O bond lengths. Sr is bonded to twelve O atoms to form SrO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with two equivalent SrO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, and faces with eight equivalent CuO6 octahedra. There are four shorter (2.76 Å) and eight longer (2.77 Å) Sr–O bond lengths. Cu is bonded to six O atoms to form CuO6 octahedramore »
