Materials Data on Sr2FeWO6 by Materials Project
Sr2FeWO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–3.07 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 19–21°. There is four shorter (1.95 Å) and two longer (1.96 Å) W–O bond length. Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 19–21°. There are a spread of Fe–O bond distances ranging from 2.13–2.18 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one W6+, and one Fe2+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one W6+, and one Fe2+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Sr2+, one W6+, and one Fe2+ atom.
