Materials Data on Ba5Fe3W2O15 by Materials Project
Abstract
Ba5W2Fe3O15 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, faces with four equivalent WO6 octahedra, and faces with four equivalent FeO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.89–2.91 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, faces with three equivalent WO6 octahedra, and faces with five FeO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.82–2.99 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six FeO6 octahedra and faces with eight BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are a spread of W–O bond distances ranging from 1.96–1.98 Å. There are three inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share a cornercorner withmore »
