Materials Data on Nd2VFeO6 by Materials Project
Nd2VFeO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.36–2.79 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 30–31°. There are four shorter (2.05 Å) and two longer (2.07 Å) V–O bond lengths. 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 30–31°. There are a spread of Fe–O bond distances ranging from 2.03–2.06 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Nd3+, one V3+, and one Fe3+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Nd3+, one V3+, and one Fe3+ atom. In the third O2- site, O2- is bonded to two equivalent Nd3+, one V3+, and one Fe3+ atom to form distorted corner-sharing ONd2VFe tetrahedra.
