Title: Materials Data on Li2NbCr3O8 by Materials Project

Abstract

Li2NbCr3O8 is Spinel-derived structured and crystallizes in the cubic P4_332 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent NbO6 octahedra and corners with nine equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 57–61°. There are one shorter (1.98 Å) and three longer (2.05 Å) Li–O bond lengths. Nb5+ is bonded to six equivalent O2- atoms to form NbO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with six equivalent CrO6 octahedra. All Nb–O bond lengths are 2.02 Å. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent NbO6 octahedra, and edges with four equivalent CrO6 octahedra. There are a spread of Cr–O bond distances ranging from 1.99–2.07 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one Nb5+, and two equivalent Cr3+ atoms. In the second O2- site, O2- is bonded to one Li1+ and three equivalent Cr3+ atoms to form distorted corner-sharing OLiCr3 tetrahedra.
