Materials Data on Li7FeCo3(PO4)6 by Materials Project
Abstract
Li7FeCo3(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.04–2.32 Å. In the second Li1+ site, Li1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Li–O bond lengths are 2.06 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.06–2.23 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.98 Å) and three longer (2.06 Å) Fe–O bond lengths. There are three inequivalent Co+2.67+ sites. In the first Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.98 Å) and three longer (2.11 Å) Co–O bond lengths. In the second Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six PO4 tetrahedra. There are three shortermore »

There are three inequivalent Co+2.67+ sites. In the first Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.98 Å) and three longer (2.11 Å) Co–O bond lengths. In the second Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.93 Å) and three longer (2.08 Å) Co–O bond lengths. In the third Co+2.67+ site, Co+2.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.97 Å) and three longer (2.11 Å) Co–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three CoO6 octahedra. The corner-sharing octahedra tilt angles range from 25–41°. There is one shorter (1.52 Å) and three longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one FeO6 octahedra and corners with three CoO6 octahedra. The corner-sharing octahedra tilt angles range from 26–39°. There are a spread of P–O bond distances ranging from 1.52–1.56 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Co+2.67+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Fe3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Co+2.67+, and one P5+ atom.
