Materials Data on Li2Cr3FeO8 by Materials Project
Abstract
Li2Cr3FeO8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent FeO6 octahedra and corners with nine equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 59–61°. There are three shorter (1.99 Å) and one longer (2.07 Å) Li–O bond lengths. Cr+3.67+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent FeO6 octahedra, and edges with four equivalent CrO6 octahedra. There is two shorter (1.96 Å) and four longer (1.99 Å) Cr–O bond length. Fe3+ is bonded to six equivalent O2- atoms to form FeO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with six equivalent CrO6 octahedra. All Fe–O bond lengths are 2.01 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one Li1+ and three equivalent Cr+3.67+ atoms to form distorted OLiCr3 tetrahedra that share corners with three equivalent OLiCr3 tetrahedra, corners with nine equivalent OLiCr2Fe trigonal pyramids, and edges with three equivalent OLiCr2Fe trigonal pyramids. In the second O2- site, O2-more »
