Materials Data on LiCoOF2 by Materials Project
Abstract
LiCoOF2 is Ilmenite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to two equivalent O2- and four F1- atoms to form distorted LiO2F4 octahedra that share corners with nine CoO2F4 octahedra, edges with three equivalent LiO2F4 octahedra, and a faceface with one CoO2F4 octahedra. The corner-sharing octahedra tilt angles range from 40–60°. There are one shorter (2.05 Å) and one longer (2.24 Å) Li–O bond lengths. There are a spread of Li–F bond distances ranging from 2.00–2.34 Å. In the second Li1+ site, Li1+ is bonded to two equivalent O2- and four F1- atoms to form distorted LiO2F4 octahedra that share corners with nine CoO2F4 octahedra, edges with three equivalent LiO2F4 octahedra, and a faceface with one CoO2F4 octahedra. The corner-sharing octahedra tilt angles range from 42–63°. There are one shorter (2.07 Å) and one longer (2.24 Å) Li–O bond lengths. There are a spread of Li–F bond distances ranging from 1.97–2.30 Å. There are two inequivalent Co3+ sites. In the first Co3+ site, Co3+ is bonded to two O2- and four F1- atoms to form CoO2F4 octahedra that share cornersmore »
