Materials Data on LiFePH2O5 by Materials Project
LiFePH2O5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.05–2.29 Å. Fe2+ is bonded to five O2- atoms to form distorted FeO5 trigonal bipyramids that share corners with three equivalent PO4 tetrahedra, corners with four equivalent FeO5 trigonal bipyramids, and an edgeedge with one PO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 2.05–2.30 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent FeO5 trigonal bipyramids and an edgeedge with one FeO5 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Fe2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Fe2+ and one P5+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Fe2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Li1+ and two H1+ atoms.
