Materials Data on YEr(FeO3)2 by Materials Project
Abstract
ErY(FeO3)2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Er3+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Er–O bond distances ranging from 2.22–2.72 Å. Y3+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.24–2.76 Å. Fe3+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 37–40°. There are a spread of Fe–O bond distances ranging from 2.03–2.06 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Y3+ and two equivalent Fe3+ atoms to form distorted corner-sharing OY2Fe2 trigonal pyramids. In the second O2- site, O2- is bonded to two equivalent Er3+ and two equivalent Fe3+ atoms to form distorted corner-sharing OEr2Fe2 trigonal pyramids. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one Er3+, two equivalent Y3+, and two equivalent Fe3+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Er3+, one Y3+, and two equivalent Fe3+ atoms.
