Materials Data on SrPr(FeO3)2 by Materials Project
SrPr(FeO3)2 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pmn2_1 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 2.50–3.09 Å. Pr4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Pr–O bond distances ranging from 2.42–2.57 Å. Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 16–25°. There are a spread of Fe–O bond distances ranging from 1.98–2.01 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, one Pr4+, and two equivalent Fe3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Pr4+, and two equivalent Fe3+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, one Pr4+, and two equivalent Fe3+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Pr4+, and two equivalent Fe3+ atoms.
