Title: Materials Data on Ba2Cu2O5 by Materials Project

Abstract

Ba2Cu2O5 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first 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 2.73–3.27 Å. In the second 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 2.73–3.27 Å. There are three inequivalent Cu3+ sites. In the first Cu3+ site, Cu3+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with four equivalent CuO6 octahedra and corners with two equivalent CuO4 trigonal pyramids. The corner-sharing octahedral tilt angles are 2°. There are a spread of Cu–O bond distances ranging from 2.01–2.46 Å. In the second Cu3+ site, Cu3+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with four equivalent CuO6 octahedra and corners with two equivalent CuO4 trigonal pyramids. The corner-sharing octahedral tilt angles are 2°. There are a spread of Cu–O bond distances ranging from 2.01–2.46 Å. In the third Cu3+ site, Cu3+ is bonded to four O2- atoms to form distorted CuO4 trigonal pyramidsmore » that share corners with two CuO6 octahedra and corners with two equivalent CuO4 trigonal pyramids. The corner-sharing octahedral tilt angles are 19°. There are a spread of Cu–O bond distances ranging from 1.83–1.89 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ba2+ and two Cu3+ atoms to form a mixture of distorted edge, corner, and face-sharing OBa4Cu2 octahedra. The corner-sharing octahedral tilt angles are 1°. In the second O2- site, O2- is bonded to four Ba2+ and two Cu3+ atoms to form a mixture of distorted edge, corner, and face-sharing OBa4Cu2 octahedra. The corner-sharing octahedral tilt angles are 1°. In the third O2- site, O2- is bonded in a 1-coordinate geometry to four Ba2+ and two Cu3+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to four Ba2+ and two Cu3+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to four Ba2+ and two equivalent Cu3+ atoms.« less
