Title: Materials Data on BaSr7Co4(CuO6)4 by Materials Project

Abstract

BaSr7Co4(CuO6)4 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Ba is bonded to twelve O atoms to form BaO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four CoO6 octahedra, and faces with four CuO6 octahedra. There are three shorter (2.81 Å) and nine longer (2.82 Å) Ba–O bond lengths. There are three inequivalent Sr sites. In the first Sr site, Sr is bonded to twelve O atoms to form SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with two equivalent BaO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, faces with four CoO6 octahedra, and faces with four CuO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.74–2.78 Å. In the second Sr site, Sr is bonded to twelve O atoms to form SrO12 cuboctahedra that share corners with four equivalent BaO12 cuboctahedra, corners with eight equivalent SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with four CoO6 octahedra, and faces with four CuO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.66–2.78 Å. In the third Sr site, Sr is bonded to twelve Omore » atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four CoO6 octahedra, and faces with four CuO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.72–2.76 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded to six O atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, corners with four equivalent CuO6 octahedra, a faceface with one BaO12 cuboctahedra, and faces with seven SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–4°. There are a spread of Co–O bond distances ranging from 1.91–1.99 Å. In the second Co site, Co is bonded to six O atoms to form CoO6 octahedra that share corners with six equivalent CoO6 octahedra, a faceface with one BaO12 cuboctahedra, and faces with seven SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–3°. There is three shorter (1.90 Å) and three longer (1.92 Å) Co–O bond length. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded to six O atoms to form CuO6 octahedra that share corners with six equivalent CuO6 octahedra, a faceface with one BaO12 cuboctahedra, and faces with seven SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–4°. There is three shorter (1.95 Å) and three longer (1.96 Å) Cu–O bond length. In the second Cu site, Cu is bonded to six O atoms to form CuO6 octahedra that share corners with two equivalent CuO6 octahedra, corners with four equivalent CoO6 octahedra, a faceface with one BaO12 cuboctahedra, and faces with seven SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–4°. There are a spread of Cu–O bond distances ranging from 1.94–1.99 Å. There are six inequivalent O sites. In the first O site, O is bonded to one Ba, three Sr, and two Cu atoms to form distorted OBaSr3Cu2 octahedra that share corners with fourteen OBaSr3CoCu octahedra, edges with four equivalent OBaSr3CoCu octahedra, and faces with six OBaSr3Cu2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°. In the second O site, O is bonded to one Ba, three Sr, one Co, and one Cu atom to form a mixture of distorted edge, corner, and face-sharing OBaSr3CoCu octahedra. The corner-sharing octahedra tilt angles range from 2–63°. In the third O site, O is bonded to one Ba, three Sr, and two Co atoms to form distorted OBaSr3Co2 octahedra that share corners with sixteen OBaSr3Cu2 octahedra, edges with four equivalent OBaSr3CoCu octahedra, and faces with four OBaSr3CoCu octahedra. The corner-sharing octahedra tilt angles range from 1–63°. In the fourth O site, O is bonded to four Sr and two Cu atoms to form a mixture of distorted corner and face-sharing OSr4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 2–60°. In the fifth O site, O is bonded in a distorted linear geometry to four Sr, one Co, and one Cu atom. In the sixth O site, O is bonded in a distorted linear geometry to four Sr and two Co atoms.« less
