Title: Materials Data on Fe(Si2O3)2 by Materials Project

Abstract

FeSiO3(SiO)3 crystallizes in the triclinic P1 space group. The structure is one-dimensional and consists of one FeSiO3 ribbon oriented in the (1, 0, 0) direction and one SiO ribbon oriented in the (1, 0, 0) direction. In the FeSiO3 ribbon, Fe is bonded in a rectangular see-saw-like geometry to four O atoms. There are a spread of Fe–O bond distances ranging from 1.83–2.09 Å. Si is bonded in a trigonal non-coplanar geometry to three O atoms. There is one shorter (1.65 Å) and two longer (1.68 Å) Si–O bond length. There are three inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two equivalent Fe and one Si atom. In the second O site, O is bonded in a bent 120 degrees geometry to two equivalent Si atoms. In the third O site, O is bonded in a water-like geometry to two equivalent Fe atoms. In the SiO ribbon, there are three inequivalent Si sites. In the first Si site, Si is bonded in a single-bond geometry to one O atom. The Si–O bond length is 1.64 Å. In the second Si site, Si is bonded in a single-bond geometry to one Omore » atom. The Si–O bond length is 1.69 Å. In the third Si site, Si is bonded to four O atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.64–1.66 Å. There are three inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to two Si atoms. In the second O site, O is bonded in a bent 120 degrees geometry to two Si atoms. In the third O site, O is bonded in a bent 120 degrees geometry to two equivalent Si atoms.« less
