Title: Materials Data on Ba3Ce by Materials Project

Abstract

Ba3Ce is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded to eight Ba and four equivalent Ce atoms to form BaBa8Ce4 cuboctahedra that share corners with twelve equivalent BaBa8Ce4 cuboctahedra, edges with eight equivalent CeBa12 cuboctahedra, edges with sixteen BaBa8Ce4 cuboctahedra, faces with four equivalent CeBa12 cuboctahedra, and faces with fourteen BaBa8Ce4 cuboctahedra. There are four shorter (4.18 Å) and four longer (4.24 Å) Ba–Ba bond lengths. All Ba–Ce bond lengths are 4.24 Å. In the second Ba site, Ba is bonded to eight equivalent Ba and four equivalent Ce atoms to form BaBa8Ce4 cuboctahedra that share corners with four equivalent BaBa8Ce4 cuboctahedra, corners with eight equivalent CeBa12 cuboctahedra, edges with twenty-four BaBa8Ce4 cuboctahedra, faces with six equivalent CeBa12 cuboctahedra, and faces with twelve BaBa8Ce4 cuboctahedra. All Ba–Ce bond lengths are 4.18 Å. Ce is bonded to twelve Ba atoms to form CeBa12 cuboctahedra that share corners with four equivalent CeBa12 cuboctahedra, corners with eight equivalent BaBa8Ce4 cuboctahedra, edges with eight equivalent CeBa12 cuboctahedra, edges with sixteen equivalent BaBa8Ce4 cuboctahedra, faces with four equivalent CeBa12 cuboctahedra, and faces withmore » fourteen BaBa8Ce4 cuboctahedra.« less
