Title: Materials Data on Ba3Al2Ga2(FeO6)2 by Materials Project

Abstract

Ba3Ga2Al2(FeO6)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three 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 2.79–3.30 Å. In the second Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.80–3.17 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 2.74–3.08 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra and corners with three GaO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.88–1.90 Å. In the second Fe3+ site, Fe3+ is bonded to four O2- atoms to form FeO4 tetrahedra that share corners with two GaO4 tetrahedra and corners with two equivalent AlO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.86–1.90 Å. There are two inequivalent Ga3+ sites.

There are a spread of Ga–O bond distances ranging from 1.85–1.87 Å. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra and corners with three FeO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.76–1.78 Å. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra and corners with three GaO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.76–1.79 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ba2+, one Fe3+, and one Al3+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Ba2+, one Fe3+, and one Ga3+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ba2+ and two Al3+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Ba2+, one Ga3+, and one Al3+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Ba2+, one Fe3+, and one Ga3+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Ba2+, one Fe3+, and one Ga3+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Ba2+, one Fe3+, and one Al3+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ba2+, one Ga3+, and one Al3+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ba2+, one Fe3+, and one Al3+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to two Ba2+, one Fe3+, and one Ga3+ atom. In the eleventh O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Ga3+, and one Al3+ atom. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to two Ba2+, one Fe3+, and one Ga3+ atom.« less
