Title: Materials Data on Li2FePHO5 by Materials Project

Abstract

Li2FePHO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with two equivalent PO4 tetrahedra, corners with two equivalent LiO5 trigonal bipyramids, corners with three equivalent LiO4 trigonal pyramids, an edgeedge with one PO4 tetrahedra, and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Li–O bond distances ranging from 2.13–2.51 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with four equivalent PO4 tetrahedra, corners with three equivalent LiO5 trigonal bipyramids, corners with two equivalent LiO4 trigonal pyramids, and an edgeedge with one LiO5 trigonal bipyramid. There are a spread of Li–O bond distances ranging from 1.96–2.18 Å. Fe2+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Fe–O bond distances ranging from 2.02–2.59 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent LiO5 trigonal bipyramids, corners with four equivalent LiO4 trigonal pyramids, and an edgeedge with one LiO5more » trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.68 Å) H–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Li1+, two equivalent Fe2+, and one H1+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Fe2+, one P5+, and one H1+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Fe2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted see-saw-like geometry to three Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded to three Li1+ and one P5+ atom to form distorted corner-sharing OLi3P trigonal pyramids.« less
