Title: Materials Data on Li2Fe(Si2O5)3 by Materials Project

Abstract

Li2Fe(Si2O5)3 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded in a 4-coordinate geometry to four O atoms. There are a spread of Li–O bond distances ranging from 1.95–2.55 Å. In the second Li site, Li is bonded in a 3-coordinate geometry to four O atoms. There are a spread of Li–O bond distances ranging from 2.07–2.61 Å. Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six SiO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.89–2.30 Å. There are six inequivalent Si sites. In the first Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. In the second Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. There are a spreadmore » of Si–O bond distances ranging from 1.62–1.68 Å. In the third Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. In the fourth Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of Si–O bond distances ranging from 1.61–1.65 Å. In the fifth Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. In the sixth Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. There are a spread of Si–O bond distances ranging from 1.61–1.67 Å. There are fifteen inequivalent O sites. In the first O site, O is bonded in a 4-coordinate geometry to two Li, one Fe, and one Si atom. In the second O site, O is bonded in a distorted trigonal planar geometry to one Li and two Si atoms. In the third O site, O is bonded in a bent 150 degrees geometry to two Si atoms. In the fourth O site, O is bonded in a distorted trigonal planar geometry to one Li, one Fe, and one Si atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to two Si atoms. In the sixth O site, O is bonded in a 2-coordinate geometry to one Li, one Fe, and one Si atom. In the seventh O site, O is bonded in a bent 150 degrees geometry to one Fe and one Si atom. In the eighth O site, O is bonded in a bent 120 degrees geometry to two Si atoms. In the ninth O site, O is bonded in a bent 150 degrees geometry to one Fe and one Si atom. In the tenth O site, O is bonded in a distorted bent 120 degrees geometry to one Li and two Si atoms. In the eleventh O site, O is bonded in a bent 120 degrees geometry to two Si atoms. In the twelfth O site, O is bonded in a bent 150 degrees geometry to two Si atoms. In the thirteenth O site, O is bonded in a bent 120 degrees geometry to two Si atoms. In the fourteenth O site, O is bonded in a distorted trigonal planar geometry to one Li, one Fe, and one Si atom. In the fifteenth O site, O is bonded in a trigonal planar geometry to one Li and two Si atoms.« less
