Materials Data on Fe3CoBi4(AsO6)4 by Materials Project
Abstract
Fe3CoBi4(AsO6)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four AsO4 tetrahedra, an edgeedge with one FeO6 octahedra, an edgeedge with one CoO6 octahedra, and an edgeedge with one BiO7 pentagonal bipyramid. There are a spread of Fe–O bond distances ranging from 1.95–2.11 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four AsO4 tetrahedra, edges with two equivalent FeO6 octahedra, and edges with two equivalent BiO7 pentagonal bipyramids. There are a spread of Fe–O bond distances ranging from 2.01–2.12 Å. Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four AsO4 tetrahedra and edges with two equivalent FeO6 octahedra. There are a spread of Co–O bond distances ranging from 1.76–2.21 Å. There are two inequivalent Bi4+ sites. In the first Bi4+ site, Bi4+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.20–2.78 Å. In the second Bi4+ site, Bi4+ ismore »
