Title: Materials Data on Li2CoPO4F by Materials Project

Abstract

Li2CoPO4F crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 6-coordinate geometry to four O2- and two F1- atoms. There are a spread of Li–O bond distances ranging from 2.02–2.38 Å. There are one shorter (1.88 Å) and one longer (2.41 Å) Li–F bond lengths. In the second Li1+ site, Li1+ is bonded to four O2- and one F1- atom to form distorted LiO4F trigonal bipyramids that share corners with two equivalent CoO4F2 octahedra, corners with four PO4 tetrahedra, and edges with two equivalent CoO4F2 octahedra. The corner-sharing octahedral tilt angles are 67°. There are a spread of Li–O bond distances ranging from 2.08–2.18 Å. The Li–F bond length is 1.92 Å. In the third Li1+ site, Li1+ is bonded in a 6-coordinate geometry to four O2- and two F1- atoms. There are a spread of Li–O bond distances ranging from 2.03–2.24 Å. There are one shorter (2.41 Å) and one longer (2.73 Å) Li–F bond lengths. There are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to four O2- and two equivalent F1- atoms to form CoO4F2more » octahedra that share corners with four PO4 tetrahedra, edges with two equivalent CoO4F2 octahedra, and edges with two equivalent LiO4F trigonal bipyramids. There are two shorter (2.04 Å) and two longer (2.11 Å) Co–O bond lengths. Both Co–F bond lengths are 2.15 Å. In the second Co2+ site, Co2+ is bonded to four O2- and two equivalent F1- atoms to form CoO4F2 octahedra that share corners with four PO4 tetrahedra, corners with two equivalent LiO4F trigonal bipyramids, and edges with two equivalent CoO4F2 octahedra. There are two shorter (2.04 Å) and two longer (2.07 Å) Co–O bond lengths. Both Co–F bond lengths are 2.16 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four CoO4F2 octahedra and corners with two equivalent LiO4F trigonal bipyramids. The corner-sharing octahedra tilt angles range from 57–60°. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four CoO4F2 octahedra and corners with two equivalent LiO4F trigonal bipyramids. The corner-sharing octahedra tilt angles range from 53–58°. There is one shorter (1.54 Å) and three longer (1.56 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Co2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one Co2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Co2+, and one P5+ atom. In the fourth O2- site, O2- is bonded to three Li1+ and one P5+ atom to form distorted OLi3P tetrahedra that share corners with four equivalent OLi2CoP tetrahedra and corners with two equivalent OLi3P trigonal pyramids. In the fifth O2- site, O2- is bonded to two Li1+, one Co2+, and one P5+ atom to form distorted corner-sharing OLi2CoP tetrahedra. In the sixth O2- site, O2- is bonded to three Li1+ and one P5+ atom to form distorted corner-sharing OLi3P trigonal pyramids. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to three Li1+ and two equivalent Co2+ atoms. In the second F1- site, F1- is bonded in a 6-coordinate geometry to four Li1+ and two equivalent Co2+ atoms.« less
