Title: Materials Data on Ba11(OsO6)4 by Materials Project

Abstract

Ba11Os4O24 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first 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 2.56–3.03 Å. In the second Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.70–3.11 Å. In the third 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 2.75–3.28 Å. In the fourth Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share faces with four equivalent OsO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.95–3.19 Å. There are two inequivalent Os+6.50+ sites. In the first Os+6.50+ site, Os+6.50+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Os–O bond distances ranging from 1.91–1.93 Å. In the second Os+6.50+ site, Os+6.50+ is bonded to six O2- atoms to form OsO6 octahedra that share faces with two equivalent BaO12 cuboctahedra. There is four shortermore » (1.94 Å) and two longer (2.00 Å) Os–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Os+6.50+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ba2+ and one Os+6.50+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Ba2+ and one Os+6.50+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Os+6.50+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Os+6.50+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to four Ba2+ and one Os+6.50+ atom.« less
