Title: Materials Data on Ca2YCuO5 by Materials Project

Abstract

Ca2YCuO5 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.31–2.96 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.31–2.95 Å. Y3+ is bonded to four O2- atoms to form distorted YO4 tetrahedra that share corners with two equivalent CuO6 octahedra and corners with two equivalent YO4 tetrahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of Y–O bond distances ranging from 2.13–2.23 Å. Cu3+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with four equivalent CuO6 octahedra and corners with two equivalent YO4 tetrahedra. The corner-sharing octahedral tilt angles are 17°. There are a spread of Cu–O bond distances ranging from 1.95–2.11 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to two Ca2+ and two equivalent Y3+ atoms to form distorted corner-sharing OCa2Y2 tetrahedra. In the second O2- site, O2- ismore » bonded in a 4-coordinate geometry to three equivalent Ca2+, one Y3+, and one Cu3+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Ca2+, one Y3+, and one Cu3+ atom. In the fourth O2- site, O2- is bonded in a 6-coordinate geometry to four Ca2+ and two equivalent Cu3+ atoms. In the fifth O2- site, O2- is bonded in a 6-coordinate geometry to four Ca2+ and two equivalent Cu3+ atoms.« less
