Title: Materials Data on Li4Ni7(PO4)6 by Materials Project

Abstract

Li4Ni7(PO4)6 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.67 Å. In the second Li1+ site, Li1+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.04–2.79 Å. In the third Li1+ site, Li1+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are two shorter (2.19 Å) and two longer (2.24 Å) Li–O bond lengths. There are four inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four NiO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 61–63°. There are a spread of Ni–O bond distances ranging from 1.98–2.09 Å. In the second Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share a cornercorner with one NiO6 octahedra, corners with four PO4 tetrahedra, edges with three NiO6 octahedra, and an edgeedge with onemore » PO4 tetrahedra.
