Materials Data on ZnFe(SiO3)2 by Materials Project
Abstract
FeZn(SiO3)2 is Esseneite structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with two equivalent FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.11–2.30 Å. Zn2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are two shorter (1.94 Å) and two longer (2.07 Å) Zn–O bond lengths. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent FeO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 42–61°. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Fe2+, one Zn2+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Fe2+, one Zn2+, and one Si4+ atom.
