Title: Materials Data on BaLaGa3O7 by Materials Project

Abstract

BaLaGa3O7 crystallizes in the orthorhombic Cmm2 space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.72–3.04 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.37–3.01 Å. There are three inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There is two shorter (1.86 Å) and two longer (1.89 Å) Ga–O bond length. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There is one shorter (1.83 Å) and three longer (1.88 Å) Ga–O bond length. In the third Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.82–1.91 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+ and two equivalent Ga3+ atoms. In the second O2- site, O2- is bonded to two equivalent La3+ and two equivalent Ga3+ atoms tomore » form a mixture of distorted corner and edge-sharing OLa2Ga2 tetrahedra. In the third O2- site, O2- is bonded to one Ba2+, two equivalent La3+, and one Ga3+ atom to form a mixture of distorted corner and edge-sharing OBaLa2Ga tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, one La3+, and one Ga3+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Ba2+, one La3+, and two Ga3+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+, one La3+, and two Ga3+ atoms.« less
