Materials Data on Ba2Y2Co3CuO10 by Materials Project
Abstract
Ba2Y2Co3CuO10 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with four equivalent BaO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, faces with two equivalent CuO5 square pyramids, faces with four CoO5 square pyramids, and faces with two equivalent CoO5 trigonal bipyramids. There are a spread of Ba–O bond distances ranging from 2.77–3.15 Å. Y3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.39 Å) and four longer (2.45 Å) Y–O bond lengths. There are three inequivalent Co+2.67+ sites. In the first Co+2.67+ site, Co+2.67+ is bonded to five O2- atoms to form CoO5 square pyramids that share a cornercorner with one CoO5 square pyramid, corners with four equivalent CuO5 square pyramids, and faces with four equivalent BaO12 cuboctahedra. There are four shorter (1.97 Å) and one longer (2.03 Å) Co–O bond lengths. In the second Co+2.67+ site, Co+2.67+ is bonded to five O2- atoms to form CoO5 square pyramids that share a cornercorner with one CoO5 square pyramid, corners with four equivalent CoO5 trigonal bipyramids, and faces with four equivalent BaO12 cuboctahedra.
