Materials Data on SrPr(CoO3)2 by Materials Project

SrPr(CoO3)2 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–3.04 Å. Pr3+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are a spread of Pr–O bond distances ranging from 2.46–2.91 Å. There are two inequivalent Co+3.50+ sites. In the first Co+3.50+ site, Co+3.50+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra tilt angles range from 14–22°. There are a spread of Co–O bond distances ranging from 1.90–1.96 Å. In the second Co+3.50+ site, Co+3.50+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra tilt angles range from 14–22°. There are a spread of Co–O bond distances ranging from 1.87–2.05 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, one Pr3+, and two Co+3.50+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+, two equivalent Pr3+, and two Co+3.50+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+, two equivalent Pr3+, and two Co+3.50+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, one Pr3+, and two Co+3.50+ atoms. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, one Pr3+, and two Co+3.50+ atoms. In the sixth O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Sr2+, two equivalent Pr3+, and two Co+3.50+ atoms.
