Title: Materials Data on Ca2BiSbO6 by Materials Project

Abstract

Ca2BiSbO6 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–2.95 Å. In the second Ca2+ site, Ca2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.25–2.88 Å. Bi3+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with two equivalent BiO6 octahedra and corners with four equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 38–47°. There are a spread of Bi–O bond distances ranging from 2.25–2.40 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 38–40°. There are a spread of Sb–O bond distances ranging from 2.00–2.19 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, one Bi3+, and one Sb5+ atom. In the second O2- site, O2- ismore » bonded in a 5-coordinate geometry to three Ca2+, one Bi3+, and one Sb5+ atom. In the third O2- site, O2- is bonded to two Ca2+ and two equivalent Sb5+ atoms to form distorted OCa2Sb2 tetrahedra that share corners with two equivalent OCa2Sb2 tetrahedra and corners with two equivalent OCa2Bi2 trigonal pyramids. In the fourth O2- site, O2- is bonded to two Ca2+ and two equivalent Bi3+ atoms to form distorted OCa2Bi2 trigonal pyramids that share corners with two equivalent OCa2Sb2 tetrahedra and corners with two equivalent OCa2Bi2 trigonal pyramids.« less
