Materials Data on TaFeO4 by Materials Project
Abstract
FeTaO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Ta5+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with eight equivalent FeO6 octahedra and edges with two equivalent TaO6 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. There are two shorter (1.99 Å) and four longer (2.01 Å) Ta–O bond lengths. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with eight equivalent TaO6 octahedra and edges with two equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. There are four shorter (2.02 Å) and two longer (2.10 Å) Fe–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ta5+ and two equivalent Fe3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ta5+ and one Fe3+ atom.
