Title: Materials Data on Li2Cr3WO8 by Materials Project

Abstract

Li2WCr3O8 is Spinel-derived structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent WO6 octahedra and corners with nine CrO6 octahedra. The corner-sharing octahedra tilt angles range from 58–61°. There are a spread of Li–O bond distances ranging from 1.98–2.02 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with three equivalent WO6 octahedra, corners with three CrO6 octahedra, and edges with three CrO6 octahedra. The corner-sharing octahedra tilt angles range from 61–63°. There are a spread of Li–O bond distances ranging from 1.78–2.01 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six CrO6 octahedra, corners with six LiO4 tetrahedra, and edges with three CrO6 octahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are a spread of W–O bond distances ranging from 1.98–2.07 Å. There are three inequivalent Cr+2.67+ sites. In the first Cr+2.67+ site, Cr+2.67+ is bonded to six O2- atoms to form CrO6 octahedra thatmore » share corners with two equivalent WO6 octahedra, corners with four LiO4 tetrahedra, an edgeedge with one WO6 octahedra, edges with four CrO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Cr–O bond distances ranging from 1.97–2.07 Å. In the second Cr+2.67+ site, Cr+2.67+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four LiO4 tetrahedra, an edgeedge with one WO6 octahedra, edges with four CrO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Cr–O bond distances ranging from 1.97–2.10 Å. In the third Cr+2.67+ site, Cr+2.67+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four LiO4 tetrahedra, an edgeedge with one WO6 octahedra, edges with four CrO6 octahedra, and an edgeedge with one LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are a spread of Cr–O bond distances ranging from 1.97–2.10 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one W6+, and two Cr+2.67+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one W6+, and two Cr+2.67+ atoms. In the third O2- site, O2- is bonded to one Li1+, one W6+, and two Cr+2.67+ atoms to form distorted OLiCr2W tetrahedra that share corners with three OLiCr3 tetrahedra, a cornercorner with one OLiCr3 trigonal pyramid, an edgeedge with one OLiCr2W tetrahedra, and an edgeedge with one OLiCr3 trigonal pyramid. In the fourth O2- site, O2- is bonded to one Li1+ and three Cr+2.67+ atoms to form a mixture of distorted corner and edge-sharing OLiCr3 trigonal pyramids. In the fifth O2- site, O2- is bonded to one Li1+ and three Cr+2.67+ atoms to form distorted OLiCr3 tetrahedra that share corners with four OLiCr2W tetrahedra and corners with three equivalent OLiCr3 trigonal pyramids. In the sixth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one W6+, and two Cr+2.67+ atoms. In the seventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, one W6+, and two Cr+2.67+ atoms. In the eighth O2- site, O2- is bonded to one Li1+, one W6+, and two Cr+2.67+ atoms to form distorted OLiCr2W tetrahedra that share corners with three OLiCr2W tetrahedra, a cornercorner with one OLiCr3 trigonal pyramid, an edgeedge with one OLiCr2W tetrahedra, and an edgeedge with one OLiCr3 trigonal pyramid.« less
