Materials Data on BaGd2Sc2O7 by Materials Project
Abstract
BaGd2Sc2O7 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.12 Å. Gd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Gd–O bond distances ranging from 2.21–2.55 Å. Sc3+ is bonded to six O2- atoms to form corner-sharing ScO6 octahedra. The corner-sharing octahedra tilt angles range from 9–34°. There are a spread of Sc–O bond distances ranging from 2.06–2.28 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, two equivalent Gd3+, and two equivalent Sc3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Gd3+ and two equivalent Sc3+ atoms. In the third O2- site, O2- is bonded to two equivalent Ba2+, two equivalent Gd3+, and two equivalent Sc3+ atoms to form edge-sharing OBa2Gd2Sc2 octahedra. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+ and two equivalent Sc3+ atoms. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-likemore »
