Title: Materials Data on Fe2Mo3O8 by Materials Project

Abstract

Fe2Mo3O8 is beta indium sulfide-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Mo+3.33+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with two equivalent FeO6 octahedra, corners with three equivalent FeO4 trigonal pyramids, an edgeedge with one FeO6 octahedra, and edges with four equivalent MoO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Mo–O bond distances ranging from 2.06–2.20 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to four O2- atoms to form FeO4 trigonal pyramids that share corners with three equivalent FeO6 octahedra and corners with nine equivalent MoO6 octahedra. The corner-sharing octahedra tilt angles range from 50–64°. There is one shorter (1.93 Å) and three longer (1.98 Å) Fe–O bond length. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent MoO6 octahedra, corners with three equivalent FeO4 trigonal pyramids, and edges with three equivalent MoO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are three shorter (1.98 Å) and three longer (2.24 Å) Fe–O bond lengths. There are four inequivalent O2-more » sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mo+3.33+ and one Fe3+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mo+3.33+ and two Fe3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Mo+3.33+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to three equivalent Mo+3.33+ and one Fe3+ atom.« less
