Materials Data on Ba6La2Ga4O15 by Materials Project
Abstract
Ba6La2Ga4O15 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are six inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to six O2- atoms to form BaO6 octahedra that share corners with six GaO4 tetrahedra and faces with two equivalent BaO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.57–2.82 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share faces with two equivalent GaO6 octahedra and faces with three GaO4 tetrahedra. There are a spread of Ba–O bond distances ranging from 2.74–3.28 Å. In the third Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.57–2.88 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.77–3.30 Å. In the fifth Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.82–3.27 Å. In the sixth Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry tomore »
