Materials Data on Ba3Eu3(Fe3O8)2 by Materials Project
Abstract
Ba3Eu3(Fe3O8)2 crystallizes in the monoclinic C2/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 four BaO12 cuboctahedra, faces with four BaO12 cuboctahedra, faces with three equivalent FeO6 octahedra, and faces with five FeO5 square pyramids. There are a spread of Ba–O bond distances ranging from 2.84–3.16 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with four BaO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, faces with two equivalent FeO6 octahedra, and faces with six FeO5 square pyramids. There are a spread of Ba–O bond distances ranging from 2.79–3.12 Å. There are two inequivalent Eu+2.67+ sites. In the first Eu+2.67+ site, Eu+2.67+ is bonded in a distorted q6 geometry to ten O2- atoms. There are a spread of Eu–O bond distances ranging from 2.63–2.84 Å. In the second Eu+2.67+ site, Eu+2.67+ is bonded in a distorted q6 geometry to nine O2- atoms. There are a spread of Eu–O bond distances ranging from 2.55–2.71 Å. There are three inequivalent Fe3+ sites. In the first Fe3+ site,more »
