Materials Data on LiFe3P3(HO6)2 by Materials Project
LiFe3P3(HO6)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.10–2.70 Å. There are two inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra and edges with two FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.09–2.23 Å. In the second Fe2+ site, Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.13–2.28 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 six FeO6 octahedra. The corner-sharing octahedra tilt angles range from 38–56°. There are a spread of P–O bond distances ranging from 1.53–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six FeO6 octahedra. The corner-sharing octahedra tilt angles range from 53–58°. All P–O bond lengths are 1.56 Å. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.07 Å) and one longer (1.41 Å) H–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+, one Fe2+, and one P5+ atom to form a mixture of distorted edge and corner-sharing OLi2FeP tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Fe2+ and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Fe2+, one P5+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Fe2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Fe2+, one P5+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Fe2+ and one P5+ atom.
