Title: Materials Data on Ba3Sr(CoO3)4 by Materials Project

Abstract

In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with two equivalent BaO12 cuboctahedra, corners with four equivalent SrO12 cuboctahedra, corners with six CoO6 octahedra, faces with eight BaO12 cuboctahedra, and faces with six CoO6 octahedra. The corner-sharing octahedra tilt angles range from 13–14°. There are a spread of Ba–O bond distances ranging from 2.84–3.03 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six BaO12 cuboctahedra, corners with six CoO6 octahedra, faces with four BaO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, and faces with six CoO6 octahedra.
