Materials Data on PrCoSbPbO6 by Materials Project

Abstract

PrCoPbSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Pr3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pr–O bond distances ranging from 2.41–2.89 Å. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 21–32°. There are a spread of Co–O bond distances ranging from 2.11–2.18 Å. Pb2+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Pb–O bond distances ranging from 2.49–2.54 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 21–32°. There are a spread of Sb–O bond distances ranging from 2.01–2.04 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Pr3+, one Co2+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Pr3+, one Co2+, one Pb2+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Pr3+, one Co2+, one Pb2+, and one Sb5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Pr3+, one Co2+, and one Sb5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Pr3+, one Co2+, and one Sb5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Pr3+, one Co2+, one Pb2+, and one Sb5+ atom.
