Materials Data on Ba2In2O5 by Materials Project

Abstract

Ba2In2O5 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.99–3.08 Å. In the second Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.98–3.13 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to five O2- atoms to form corner-sharing InO5 square pyramids. There are a spread of In–O bond distances ranging from 2.01–2.16 Å. In the second In3+ site, In3+ is bonded to five O2- atoms to form corner-sharing InO5 square pyramids. There are a spread of In–O bond distances ranging from 2.01–2.16 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ba2+ and two In3+ atoms to form a mixture of distorted edge, corner, and face-sharing OBa4In2 octahedra. The corner-sharing octahedra tilt angles range from 1–60°. In the second O2- site, O2- is bonded in a distorted linear geometry to four Ba2+ and two In3+ atoms. In the third O2- site, O2- is bonded to four Ba2+ and two In3+ atoms to form a mixture of distorted edge, corner, and face-sharing OBa4In2 octahedra. The corner-sharing octahedra tilt angles range from 2–61°. In the fourth O2- site, O2- is bonded to four Ba2+ and two In3+ atoms to form a mixture of distorted edge, corner, and face-sharing OBa4In2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°. In the fifth O2- site, O2- is bonded to four Ba2+ and two In3+ atoms to form a mixture of distorted edge, corner, and face-sharing OBa4In2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
