Materials Data on Zn2Fe3O8 by Materials Project
Fe3Zn2O8 is beta indium sulfide-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form edge-sharing FeO6 octahedra. There are four shorter (1.99 Å) and two longer (2.02 Å) Fe–O bond lengths. In the second Fe site, Fe is bonded to six O atoms to form edge-sharing FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.93–2.03 Å. Zn is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Zn–O bond distances ranging from 2.04–2.27 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to two equivalent Fe and one Zn atom. In the second O site, O is bonded in a rectangular see-saw-like geometry to three Fe and one Zn atom. In the third O site, O is bonded to two Fe and two equivalent Zn atoms to form a mixture of distorted edge and corner-sharing OZn2Fe2 tetrahedra.
