Title: Materials Data on Ca2CuWO6 by Materials Project

Abstract

Ca2WCuO6 is Orthorhombic Perovskite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.42–3.12 Å. In the second Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.47–2.85 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent CuO6 octahedra. The corner-sharing octahedra tilt angles range from 6–10°. There are a spread of W–O bond distances ranging from 1.91–1.97 Å. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with six equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 6–10°. There are a spread of Cu–O bond distances ranging from 1.97–2.22 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, one W6+, and one Cu2+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, onemore » W6+, and one Cu2+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to three Ca2+, one W6+, and one Cu2+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Ca2+, one W6+, and one Cu2+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to three Ca2+, one W6+, and one Cu2+ atom. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ca2+, one W6+, and one Cu2+ atom.« less
