Materials Data on La2VFeO6 by Materials Project

Abstract

La2VFeO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.38–2.88 Å. V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 27–28°. There is two shorter (1.91 Å) and four longer (2.00 Å) V–O bond length. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent VO6 octahedra. The corner-sharing octahedra tilt angles range from 27–28°. There are a spread of Fe–O bond distances ranging from 2.08–2.17 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent La3+, one V3+, and one Fe3+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one V3+, and one Fe3+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one V3+, and one Fe3+ atom.
